Sometimes people say everything shouldn't be about you. That's true. Everything shouldn't be about you but somethings can and should be about you. There's nothing wrong in showing yourself some love. Take care of yourself from time to time. They'll say it's bad to be self-centered but it's also not bad to do something good for yourself for once. It's okay to take that opportunity for yourself. Expending your energy and resources to make others better is good but not at the expense of your dreams and goals. Treat others the way you'd like to be treated and treat yourself also the way you'd want others to treat you. Life goes on either ways. Nobody can treat you better than you so work on yourself and be a better person all round.
