Would you like me to give you the way to think and build up an advantage in this forum?
Losing Streak.

Even after learning more things like don't take every pawn with your pawn that you can and make sure your pawns are also protected and me taking time on games instead of moving in the first 10 seconds, I am not improving.

Its very hypocritical of me to say this, but play less simultaneous games. Its not really about how much time you spend on chess but what you do with your time. Try some of the lessons on chess.com and (if you have time) play some slow live games (around 15+10)

Learning new stuffs will likely dip your performance initially due to two reasons
1. Unfamiliar stuffs ( slow decision)
2. More checklists ( slow decision).
Your brain will sort out later which checklists to keep and which one to get rid of.
Top players dont consider A-Z checklists like beginners. ( Consider what experienced drivers do vs what learners do)

*coughs* I've done and complete those 2 years ago.

My advice: just keep playing! Also, try the tactics, and try playing some rapid.
Done.

Lessons? I've done 300 of them.

That's asking me to act like I'm okay with losing... I am, but now 18 out of 20 times. I could try, but that's not easy.

my daily rating has improved by 182 point in last 30 days, i.e, from around 1400 to 1600 hundreds by learning from my own thread.

I'm not a very good player myself, but just want to share my 2 cents. In daily games, ask yourself:
- When your opponent plays a move – what is the purpose of his move? What was this piece doing in its former position, and what is it doing now? (Remember, moving a piece may allow it to control new squares, but it often loses control of previously controlled squares, too.)
- When you decide to play a move – why should I play this move? What was the piece doing in its former position, and what will it do now? Can my purpose backfire? Is there any better move?
And for now, do not attempt to learn something new, just try to apply what you know in your games. Hope these will help!

Thanks; I've been doing that... maybe there's more.

I haven't got good advice yet on this forum; only by a message I got. Guys, I've been through this before and doing your tips never helps.
