First of all the Nimzo isn't a solution for just one defense because white can avoid it. You'll need a companion opening like the bogo, queen's indian, or queen's gambit declined.
That plus there are a number of different pawn structures, so IMO it's not an ideal first choice. You might be more comfortable starting out with a QGD then after a few months going to a nimzo.
But ok, if you want to learn it, get a book and look at a lot of GM games. That's my advice.

Yes if they play the "anti nimzo" Nf3 I think it is?... I play d5, QGD and pray basically...
My pet anti london system is in the QID family, so maybe I'm just confusing ideas from these different approaches...
I've tried Bogo too but I didn't like it as much..
Yes I have been looking at some GM games and as for a book can you recommend one? I study some free thing on chessable but this is the thing I am finding hard to really internalize...
You'll definitely have to resort to help from outside sources since the Nimzo is pretty complicated.

Yes yes help me find the best sources mr. FM!
I'm just an amateur but still I feel like exploring this complexity..
I don't like chess books for openings so I can't recommend a book, sorry. I like to get 10-20 GM games from an opening variation or structure and go over them at a quick pace. I also like to use a database so I can choose which variations I like instead of having an author choose one for me.
There is a video series available to premium members on chess24 by Jan Gustafsson (his videos are typically pretty good).
I'm sure if you look up Nimzo Indian online you can find some free videos/sources as well
I see the general consensus is that the Nimzo is had to learn. I respectfully disagree. I don't think it's easy, but I don't think it's hard because many of the pawn breaks and moves to attack White's structure are thematic and can be played in many lines. At my level, I almost always equalize with the Nimzo, and often times I can give White a hard time. Although I can understand not choosing it for complexity.
The Nimzo isn't simple, but it's not the Theory of General Relatively either. If you like books, "The Nimzo-Indian: Move by Move" is quite good. If you like videos, Jacob Aarsgaard;s "The Nimzoindian Defense the easy way" is a great introduction

Cool yes I like Jan's e5 stuff so i'll look if I can find some of his stuff for the Nimzo.
The thing is when I watch videos they just go through lines and I can never remember the ideas in games - especially in the so called "less theoretical" d4 stuff to which everyone of my opponent seems to know theory very well... less theoretical yeah right... Anyways thanks and if you recall something specific please share bro

I'm not sure about how much of a consensus it is... I think the reason I started learning it is because someone had said it's relatively non theoretical and easy to learn... Now that you guys are saying it's considered complex I'm feeling a bit less stupid that I'm struggling with it I guess... But maybe just struggle is good.
Refer to chessable gm surya shekhar ganguly has absolutely mind boggling course of nimzo
A short free version with 33 trainable lines against popular choices by white and then if you r interested you may buy full course for 100$
Somehow my brain just refuses to get the Nimzo, but I don't want to give up on it just yet...
Help?
If you want an intuitive, "easy" approach:
- Put the bishop on b5, to pin the c3 knight.
- Castle
- Put the d-pawn on d6
- Queen knight goes to d7
- Queen bishop goes to b7
- If white castles (removing the pin on the c3 knight), capture the knight
- Queen goes to e7 or c7
- Look for an e5 or c5 pawn break (pawns to dark squares, to avoid impeding your b7 bishop).
Example line
Of course, as you get more experienced with the Nimzo-Indian, you'll start learning about different move orders, certain moves to look out for, when to prevent white from playing e4 (and when to allow it), and alternate development schemes.
(In some lines, for example, the queen knight goes to c6 then a5, to combine with the queen bishop on a6, to hit white's doubled c-pawn ...)
But the above approach should be enough to give you a general starting idea.

Ah thanks for this!
Yes, this sounds like the simple approach someone once told me about that got me interested in this... Then I got a chessable course and it was very complicated I assume it's addressed to 2000+ players looking for the most critical stuff.
for example in nearly all lines you fight for the center there with d5, and d6 is rare...
so there are weird direct ideas with early c5 and d5 or both, it gets really tactical quick and also really different, like the lines are very different from one another with one move working in one line and completely ruining another similar one...
so again thx you rock bro
Glad I could help. 
Yes, the Nimzo can get complicated ... but it doesn't have to be. You can play it in a simple way, to avoid all that theory ... and only dive into the complicated stuff later, if you want.
depending on what lines you play, nimzo can be simple, almost system like, to intuitive to very complicated. Some lines like the zurich, or the b6 nimzo-QID hybrid lines are not hard at all, whereas others can get pretty deep
Study the Nimzo all you want, then your opponent will play 2. Nf3 or 2. Bg5 or 2. g3 etc. and you'll need a response for all that too.
I take my words back, the Nimzo doesn't have to be difficult depending on the lines one chooses, but I think you'll still have to resort to videos/books/lectures to be able to find such lines
The nimzo is good opening and hard to learn
Man common if you choose to learn openings like nimzo, grunfeld, najdorf, ruy lopez, catalan you do need to work hard very hard
So I think you should not search the lines easy to play learn all the lines and put your opponent in a unknown position
This "flamingo" approach is by far my favourite way of playing/teaching the Nimzo-Indian, which also equips you against 3.Nf3 and 3.g3 since you can play the same plans against all of them. Probably the easiest Nimzo approach to learn and start playing immediately for weaker players too.
I chose to learn the Nimzo just because I relate to the idea of using one defence as black, and since I have a pet opening against the London that begins with Nf6, e6, which I love and have good results in, so the Nimzo seemed like a natural choice for me.
However I find studying it a bit non-intuitive. I'm an e5 player and also an e4 player as white, so I feel quite at home slowly expanding and getting more familiar with all the e5 stuff as black... But the d4 c4 players who know what they are doing just boss me around, and studying is hardly effective... Somehow my brain just refuses to get the Nimzo, but I don't want to give up on it just yet...
