[a_a_r_o_n]

What's the software service or app or tool that you most want to have, that would make the hair on the back of your neck stand up when you say "I built that?"

Build that. Or build a small piece of it. Or build a prototype of a small piece of it.

In other words, build something, anything, that makes you want to get up in the morning and skip school to work on it all day. (But don't skip school.)
