I sometimes have the following thought (disclaimer: cringe is not the most adequate word for the concept in my mind, but since you've already used it, I guess it's okay): If I look back at my 10-year-younger-self and cringe (at the things I did/said/created/liked/hated/etc. and I obviously do cringe), does that mean that I am being cringe right now? Or at least, how can I have some level of confidence that I'm not being cringe right now and that in 10 years I'm not going to reject everything and anything I'm saying today? And if I was cringe 10 years ago, and if I'm cringe right now, will I be also be cringe in 10 years too? What about 20? 30? Will it ever stop? Will I ever reach a point in which I will not cringe?

Another one is like this: There are people who I respect/admire for the things they did, and now they are doing something obviously completely stupid. Were those things they did just random results I got to see, compared to a bunch of other stuff they probably did I did not get to see, thus creating this sort of false image of their intellect (or character, or something like that), or are they actually right in believing in this new thing, and I'm just being oblivious? How come some really smart people do some really dumb stuff (while believing they are doing the right thing)? I believe I'm somewhat smart, but what does that even mean if it doesn't prevent me from doing some really, really dumb stuff.

At some point, my friend told me something like (or at least this is how I understood it) - it is good that you realize that good/smart people do bad/stupid things, and vice versa; the fact that you start from this belief that you might be wrong gives you a greater chance of being less wrong, at least in the long run.
