Ok, I was a little tongue in cheek, so I agree it's a bit more complicated than just asking any question that pops into my pretty little head.
But I do think that not worrying about whether people will think I'm ignorant for asking is a very important first step that I could have applied successfully when younger. Confidence is hard earned though.
When explaining stuff I've been working on to others I often tell them "what the fuck?" is a suitable question (to try and lower this barrier) :)
