That doesn't really apply to me since my internal motivation dies out pretty quickly and if I force myself to keep going I only get worse and worse results and start hating the things I love.

I don't really get a lot of internal satisfaction or at least not enough that keeps me doing something. If I notice I start losing motivation, it's better for me to stop and pick it up again when I feel motivated again (which can take months or years).

I enjoy the process of learning something new.
