Yes this is what I tell myself to keep from going insane, I learned a lot. Unfortunately the majority of these skills I've acquired are not applicable to "pay the bills" work. By trade, I'm still building web forms and streamlining internal business processes - what would it look like I spent those years on perfecting that craft instead? What if I didn't block out my evenings and sacrifice time with friends and family? Life is always a series of trade-offs, I suppose.
