Short and sweet lesson of life is being selfish. I know this sounds harsh and it is often very difficult, but it is important to think of yourself when making decisions. There is a difference between being selfish and being egotistic, so be careful when establishing the balance. Do what makes you happy, because somewhere down the line someone will always disapprove and disagree with you no matter how much you try to please everyone.
And only this one time – just this one single individual time – do I think that the saying YOLO is appropriate: You only life once – cannot think of a better place for this annoyingly stupid acronym.
Note: Do not annoy people for entertainment purposes, that does not classify as fun even though it is easy.
