"how can i improve myself"
++ Always check your intended move is no blunder before you play it.
Whenever you lose a game, analyse it thoroughly so as to learn from your mistakes.
"chess is hard for me to win" ++ First focus on not losing. Wins will come.

It's not true that you lose all your games.
In the short time you have been here, you have won 16 and lost 16 games, establishing a 1500 rapid rating.
That means that you are better than most of the players on the site.
You may still be a million miles from the top, however. That's why you need to take advantage of the lessons and drills here to see if you can improve.

Getting better at chess is a fool's errand.
You realize you just said this on a website made for helping players at chess, insulting 90% of the playerbase, right?

I think after a bit of time, many will come to the same conclusion.
Getting better for a vast majority of people simply results in winning and losing the same number of games, just to people will bigger numbers next to their name.
None of your typical friends and relatives will play you because they know they will lose.
even though winning and losing is not supposed to be a indictor of skill and improvement -- we as weak humans remain tied to that scale -- i in my own time here still worry about winning and losing -- even though deep inside i know its all !@#$%hit- i still crave to win - even though losing is when i get better - well in my head i hope thats the case --so take heart 1400 games is not all that many --to really start to improve -- unless you are gifted to the game or a fast learner or have a constitution of a winner waiting for the turn in the road -- keep going take heart --one of those three you are -- you'll get there

You already have a high rating. However, it is best to do a Game Review after a loss. The coaches will explain what you did wrong and what you could do better next time.
