This is something I've been doing for some time now and I am not sure if it's healthy and the right way to build a better character. The point is that I recall bad experiences, just big failures on my side to instill the sense that I should be better than that. However each time I recall it, I feel strong cringe, I feel really bad in general, like I am mentally challenged or something and I am not sure if this is the correct way to move on to being a more successful version of myself.

The only way of getting rid of these thoughts is to start fresh, to consider that I haven't existed before today and I just should move on and do things efficiently with a great rate of success, otherwise it's pointless. That option is not ideal too, since I can't literally forget everything just like that but to be honest considering my dating experience, I really don't want to remember it ever again.
