That's true. And answers that seem obvious later, aren't obvious when you're young or less informed.

My personal example: I had to do a lot of research, distillation of sources, and so on, in about 2001, to figure out the answer to a simple question:

Can a person truly be a professional poker player--that is, be able to profit consistently in a proveable way, not some kind of lucky tournament win and then you masquerade as a pro--or is that a bullshit dream held up by a few desperate gamblers?

I recall it took about a week before I felt confident about my answer and I had to overcome my own bias.
