Think about what you really want and what makes you truly happy .
To not die; to not age; to experience continuous growth (not in the pituitary gland/gigantism way...)
Each to their own, but that sounds FU.
You could try vampirism...
Don't do things to make others happy
Each to their own, but that sounds FU.
In my experience when you do something solely to make someone else happy it makes you unhappy and bitter. It can destroy that relationship and result in a bad situation for both people. You resent that person for making you feel like you had to sacrifice your choice or happiness to help them obtain theirs or their perception of you. It usually backfires and creates a worse situation.
For example... a father pressures his son to following in his family's footsteps as a doctor when what the son really wants to do is be a software developer. The son begins down the path of schooling and requirements to become the doctor his father always wanted him to be. One day the son realizes he is truly unhappy in this career and choses to follow his passion of software development. He drops out of school and his father is angry at him for the wasted time, money, and for not achieving the "ideal career path". The son resents his father for the same reasons as well as himself for never following his own passion.
Sometimes you just have to be you and stand up for yourself. Being "selfish" is often looked at as a negative term... let's refer to it as self-love then.
Doing something to make someone else happy because it also makes you happy is a different thing...
