If it is to be, it is up to me
To me this is saying i can do anything i want if i put my head into it.Like for example if i wanted to become physically fit i could give up certain foods to better myself.Even workout more often maybe get a buddy or friend to help me with my working out.Saying nothing is a "I cant do thing".Hard work and dedication and make you go farther then you would ever guess you would go and once you see the results you would be more motivated to continue and maybe even get another started at the same time.
