So much this! My learning curve on crypto took me through a few self-evaluations:

- Crypto isn't that hard! I can do this!

- Crypto is a lot harder than I though. I shouldn't do this.

- I've read about a lot of crypto! I can do this!

- People way more experienced than me are making the tiniest mistakes that end up crashing the entire house of cards. I definitely shouldn't do this.
