I think a-lot of successful people often exaggerate their nostalgia prior to their breakthrough. Of course, human beings are wired to pursue things that we don't have and successful people are no different. Despite what they say, I wouldn't think many of them would go back to that life again and battle through it all if they could help it.
For me, I like to think that today is the happiest day of my life , but tomorrow is an even happier day. I cannot bare to think the consequences of living past point at which I thought I was at peak happiness. I would probably commit suicide..
