Or maybe he thought it wasn't going to last? It's one of his recurring themes(/fears?) that it's all going to end.

I think it started with him saying his career would be over in a year. Last year when I saw him he said "two, maybe three years tops" before people would forget about him, and now I guess he feels a little more confident that he'll be sticking around for a while.
