Pick up a course, or like in my case a book and start. Try to understand as much as you can, try to write some easy programs that will maybe calculate, convert or display something. Anything, basically. You can always start a course that teaches you straight from the beginning for eg. boe to build a game, website or anything you're interested in. Just one thing to remember. Never make breaks that will last longer than 2 days. Keep on pushing and follow the course. Then you'll definitely achieve something worth your time.
