Do any of y'all cut your own hair?

Disclaimer: I'm talking about masculine haircuts, but NOT crewcuts or buzzcuts. I'm talking about something like Maverick from Top Gun or something similar.

Do any of you cut/trim your own hair? How much of a reckless idea is this? Is it possible to learn how to do it? Will me having thick hair make it harder? I heard of some people doing it, but others tend to say it's a reckless idea.

I'm just considering this in case I won't be able to afford trims.
