Let me tell you a story...
When I was 20-21 years old, I thought I would be married by 24 and
by 26 live the dream "white picket fence, a wife, a stable job a
kid (more to come)". Now I'm 31, and I can't shake the feeling I
might have done something wrong in during the past decade.
So one day, recently, I made myself a pot of hot tea, and I have
looked back at all of my past. There was nothing there I have
regretted, not then and not now. Sure now that I know how certain
decisions have played out, there might have been times it might
have been better to do something different... But would changing
those decisions (decisions which I made to the best of my ability
and with information I had at the time) be better for me?
I am happy right now. Not married, but otherwise happy. If I
changed something about my past, I wouldn't be here, now (?) and
chances are I could end up unhappy.
I suppose what I am trying to say is that sticking to your
principles and requirements will force you to cross many rough
patches, but at the end things have a tendency to work out for good
