I would like to share with you some links where you can find great online courses, what are called now MOOCs (Massive Open Online Courses). There are plenty of topics, as well as languages available.
The best is that they are free, unless you want a certificate, which is pretty affordable anyway :)
Do not waste your time, learn about things you are interesting in!
