It's about another time for a graph

This doesn't have to do with the big, important things in life. But I do get a lot of awesome (at least I'd consider them to be awesome) ideas of ways to entertain myself / my friends in my spare time.

Unfortunately, most don't come to fruition because of the curse of "diminishing motivation" related to awesome ideas.

As per usual, a graph represents my thoughts sufficiently. You can click to enlarge if needed.

Any ideas on how to improve this curve?
