Yes, fighting yourself is very consuming as well as fighting others. I think we should let us be OURselves. I should be MYself, you should be YOURself and other people should have a chance to be THEMselves. We shouldn't fight ourselves and we also should let other people be themselves and not try to change them all the time. I always try to remember that...
Thank you for your comment @lindiry :)
When I wrote this it was actually meant for myself, because I do a lot of splashing around and fight myself a lot. It is draining my energy and therefore I am student of being at peace. Even if it takes my entire life, it is only way I see myself be myself.
