Work with others who are better than you. You will be instantly pressured to step up your skills. Being around others of a higher skill level allows you to see how they do things and where you can improve.

I see that open source is encouraged, but you won't have the same drive as you would if you are working on your own project.

So find someone that is better than you and work on that cool idea that you always think about; we all have at least one.
