As you undoubtedly know already, this largely depends on what you want out of Go, and on your mentality.
Of course, it is natural to want to win. If winning is so important to you,
you can easily create a new account to sandbag and win 99% of the games
(losing on the occasional blunder or to another fellow sandbagger.
)
But that's not the point and you know it.
When you play someone of your level, or when you play a fair handicapped game,
you also know you'll win 50% and lose 50% on average. So that's not it, either.
The only sensible thing left, at least to me, is to try to make the best move,
one at a time. Don't play a move that I'll regret later.
Of course, afterwards, when a good teacher reviews the game,
all the mistakes, big and small and ugly and stupid, will be pointed out to me.
So back to more studying, and try to do better the next game.
Then winning or losing is not the end but only a means.
I feel lucky that I'm not a pro, whose wins and losses directly affect a livelihood (and family).
I hope you will eventually work through this stage.
When you feel proud about the efforts you put into your studies
and into every move, and you feel good about a game whether
you win or lose, then you will have much improved.
