I used to snowboard 30 days a year. Now its down to eight.
Do what you love and the rest will come.
Build something that fixes something people are having a problem with, and you're lined up for great things.
If there's something you want to build, but the tech isn't there yet, just find the closest possible way to make it happen.
People can copy what you've done, but they can't copy what you still want to do.
Stop sketching and start building.
