I know more about some things (e.g., UX design, mentoring, etc.) and far less about many other things. I bet we could teach each other something!
I need help with spreading the word that I'm streaming design at twitch.tv/ux_adam Tuesday-Thursday, so that I can connect with and help even more designers.
Perhaps the best advice I've received was, "If you want to learn something really well, teach it to others."
Without effort, I remember how incredibly lucky I am.
If I only had 5 minutes, I would teach someone a couple ways to save time (or stretch it out), through using tools to shortcut or automate tasks, watching videos at 1.5x or higher, injecting novelty into their day, etc.
