Thanks for the words of advice, definitely has me thinking.
But to get started, just get stuck in building some web app that helps you or is funny to you, and throw it on heroku as a project. Put everything on github and begin growing your coding resume that way.
A software engineer friend was telling me last night why it's so hard and exhausting to learn. It's because you use so much thinking power learning something new, but the more you do it, the more it's muscle memory, like driving a car. Maybe 80% of the time you spend learning will actually be tiring and boring and hard. So, it's probably going to be painful at first, but having the drive to complete projects and get stuck in will get you where you want to be (even if you can't decide where that is, yet :) )
One warning would be to stay away from just learning languages. Logic and syntax are important for sure but knowing all the tools needed to build one piece of software is where you gain useful skills.
