How can I improve?

What is the quickest way for me to improve?

I play and watch videos on chess everyday.
I analyse some of my losing games and never really understand why the computer does certain things.. Especially at my level (900) the opponent wont respond how the computer does.
So would it be better for me to just do tactics and learn traps that lower players like myself will fall into? Or learn certain openings and lines to get more knowledge?
Or just continue to play and learn the way I am?

Thanks

Bullet and blitz are great tools for the intermediate player to improve with but at your level all you are doing is perfecting your mistakes.  Study your Lessons instead.  I know, more work and less fun, but you want to improve, right?

Yeah see i thought that too. 
I fall into the same traps a lot in fast games haha.

I never learn so I try a different opening and still feel like I'm making silly mistakes.
I actually started back into the lessons again. But I have done the beginner and intermediate ones all once or twice then played games.
I feel like I shouldn't progress to advanced until I'm sure I myself have advanced.

Thanks for the reply will look into more of these lessons and I have books even I dont mind boring as its still interesting for me to know im improving. Im sure it'll only get boring when i reach more of a plateu
