I understand why you are saying this, I really do, trust me there have been so many times that I wanted to do that. Having sat at home for years, doing nothing, no job, almost no contact with the outside world etc. I definitely would not have been sad if I could have skipped that part of my life.
For me that was a dark part of my life, a time I do not like to think about, most of the time it just feels like I actually skipped that part of my life. But I obviously didn't. It's poop to feel crap, it hurts and so many other things, but it teaches you. I know that everyone knows that, everyone knows those expressions of what doesn't kill you, only makes you stronger etc. Frankly I do not give a crap about that, what I do care about, is that with my experience I'm able to help others, to be there for them.
So you do not want to skip parts, even if they are poop, because we all go through different levels of poop and if you use the experience in a positive way, you will be able to do great things with it.
