Of course not, but we all have our own life-story, genetics, background and we age and evolve/devolve mentally and physically in our own way.
What was "the life" for Johnny at 20 may not be the same at 35 etc
Well IMHO "the life" doesn't happen by accident (even if it may seem like that sometimes). On the other hand - as most ppl doesn't have a fukkin idea of what they want to accomplish in that "life" and "go by the flow" - it's no surprise that "life happens" somehow to them.. Look at all the succesfull people who accomplished highs in what they loved - none of them let life "just happen", they MADE it happen the way they wanted it to..
But overall I agree that everyone won't be R.Robinsons and T.Freemans or B.Gates'es... it's just that I can't stand excuses (well if a person doesn't complain - it's all good, priorities changed, life changed, everything is dandy. But if one goes "Oh my I have 3kids now, so I can't let myself to go to the gym 5times/wk" the question arises "Well buddy - why the hell have you let that happen in the first place??"..).
