Join an open source community that is welcoming to newcomers (e.g., BRL-CAD, Haiku OS, OSGeo, ..) and work on a little bit of code every day. It can be a simple feature, specific bug, or something new you want to achieve. Many open source groups are very welcoming to newcomers if you do the work and ask smart questions.
