It's the same thing all the time

Fighting for something I don't need for. It is always the same thing and cannot avoid.

Am I mentally retarded?
Will I ever learn from my mistakes that I have been making?

How would I know? There is one thing that I discovered that was mistake and I can successfully avoid from the same mistake, but then there is new mistake that I make again. People or time, timimg, conditions are diferrent always.
I just cannot help wonder how people are handling their lives.
