We are not born guilty. Guilt is something we learn as children, from parents, from teachers, from peers. The real question is, who were you trying to please with the "be a man, have a wife and children" stuff? Certainly not you. That whole thing fell into the "I'm doing what I'm supposed to be doing, really well" thing. But who the heck did the supposing in the first place? Again, not you.
For too long, you have been an acolyte of the religion of BMOC (Big Man on Campus), where the mantra goes, "If I can have the right girl, the right kids, the right house, the right career, then I can achieve nirvana."
I know too many people who worked themselves to death trying to live like that.
It is time for you to realize that the "rules" you think you are violating don't exist. They are just dark phantoms in your mind, planted by the thoughtless words and actions of other people.
Stop living for the phantoms. Live for yourself.
