I totally understand the part about not giving you 100% in case you don´t succed. I had the same feeling a few years ago, for me it was: Ok, I consider myself very capable in a lot of areas, but to actually try to achieve something and not getting it, might show me how capable I truly am, sort of a reality check. The truth is, I didn´t. I have gotten pretty much everything I strive for and that is very fulfiling, sometimes you just have to take that leap off of your comfort zone and magical things will hapen, we are capable of so much yet we don´t do it because self doubt is always there to haunt us. The moment I realize that, my life took a sudden change which I am loving.

Well, to get rif of the inner critic, for me it works perfectly to do the things I wouldn´t do. If old Eric would never dance roomba in public because of embarrasment, present Eric actively searches for dancing situations to deal with that embarrasment; if old me would not speak with girls, present me starts conversations with every girl I see, and even if it goes horribly, you learn from everything, you become a better person, you come one step closer to being the best version of yourself you can be, and that feeling is awesome.

You don´t even need to make a list about these things. When you encounter a moment where your answer would be no, make it a yes, a hell yes, a "let´s do this now" yes.
