I think studying in a group is more fun than studying completely alone and it might help one to stay motivated. Sadly, it is not always easy to find a local real life group so I am thinking this thread could be a such group. The idea is that we all together, in this thread, decide upon a textbook and we move forward in the same pace so we can discuss the exercises with each other.
If you think this would be something you want to join, just post in this thread.
