Business Genius...in alternate Stargate universes only!

I only play business geniuses in alternate Stargate universes! But as a fan of the indiehackers podcast I'm hoping that this forum might be able to offer a few suggestions and/or simple advice to share with my TechBandits Kid's Club (10-26yr old) to get them inspired about getting started in business and entrepreneurship (our focus is Science Technology Engineering Arts and math but teenagers love money too, it seems! ;-) ...I've also asked on social media and here's what I've got thus far:

Get a mentor (I'd really appreciate experiences on how best to do that!)
Embrace failure (which I thought was a great one...if anyone has any experiences to add to that)

Thanks in advance you big business brains!

Cheers,

(PS... is there a more suitable group (or groups) I should be asking this in?)
