For those of us lacking motivation (me), burning out too quickly (me)

I'm wondering if there are any online communities where, in order to remain in the group, you have to produce code or contribute to the group's projects? Right now I'm learning C# and OOP, and I have some knowledge in Python, JavaScript, C, C++. C# is my focus. I'm older (50's) and do not work in IT or any programming endeavour. But I have *potential*, I say that because I did take programming courses many years ago in different languages and did well.
