I don’t understand why some people are so selfish, why life so hard, why we live and deal with so many problems?

But most of all I don’t understand why we fight so much to get through these problems, why do we give in all are effort to try and fix it, why is the reason we all go through it?

What I do understand is no matter what life throws at us god only gives us what we can handle, why we do everything we can to smile and just forget about what’s happening in are surroundings, why I don’t let the little things or anything in life stop me from getting to where I want to be.
