Yeah, you live and learn. Secretly, nobody ever really knows what they're doing. The whole of humanity, everybody, is just doing whatever; throwing random stuff at a wall to see what sticks. That's life and I love how humbling that is.

When you get experience, you learn to recognise what kind of things are more likely to stick to the wall. But than life changes and switches your wall for a different kind of wall and all your presumptions are now wrong. You have to learn it all over again, but you notice that you've developed a nag for finding the patterns. So it took you a lifetime to learn what kind of stuff sticks to your first wall. But you're figuring this second wall out it mere months.

... I'm sorry if I've lost you by now, but I like making analogies haha
