The problem when you ithgetting better

Do you find that the above statement don’esn't make any sense?

I believe that a more natural way to say this would be 'do you think that the above statement doesn't make any sense' or 'does the above statement seem to not make sense?'

AnEveryone wants to become better than others.

I also believe that a more natural way to say this would be 'everyone wants to become better than the rest' or 'everyone else'

Why is there is a problem?

Therefore, I need to put more time to devote more time.

It sounds better to me to also include 'to it' or to whatever you're referring to after 'time.'

At the same time, I am losing the enjoyment of other “things”!

But now I need to putspend more time to study Japanese, physical training…

'devote more time' could also sound a bit better.

So, I shouldn't be no good at anything thenso that I can enjoy many things.
