There’s an odd thing about pleasure – it changes as things happen.
If I want to watch a movie, I have a lot of pleasure finding out about the movie, I write it down, I’m excited. Then, as time passes by and I watch the movie, the pleasure decreases.
If I’m thinking about chocolate there’s a lot more pleasure before the process than in the process itself.
If I want to meet someone, I’m happy before the meeting, and partially happy during the meeting, but, at times, less happy. Do I wish to see a dear person again? Sure. I meet him/her, and I ignore him/her.
Preparing for a run is not the same as doing the run itself.
