Of course. And that's a very valid want. You're at this point because you came to an understanding about yourself and that you don't have to let those issues define who you are. At the same time, who you are today is very much someone who faces this challenge, and this is intrinsically a part of your identity. This is neither good or bad. There's no judgement or value attribution here. The observation here is that you wouldn't be who you are today if your life took a different road, either by your own choice or by circumstance. My point isn't that life is pre-destined or pre-determined. Each moment is an opportunity to do something that pushes your life in one way or another. But the opportunities and the choices life hands you? Those aren't infinite and neither are you in complete control over what will cross your road. Sleep, eating, stress management, exercise,... those are all good habits that will help open doors to other sets of opportunities and choices which you wouldn't have if you didn't mind them at all. But in my view, the author overstates their importance to the point where he simply ends up disregarding many other factors that determine one's mental well being which often have a larger impact.
