I've recently had an idea that I'm really excited about, but it's totally outside of my wheelhouse. It's a biotech idea and I have no training in biology or chemistry. I started watching open courseware lectures but then decided to try using a biology text book instead. I went to a local salvation army and picked up a biology book for $2. It's been working pretty well, but I'm trying to figure how to self sustain my motivation. That's always the hardest part of self learning for me.
