“Need to optimise out energy-output to reward ratio”

Yep, I need to make sure I somehow get enough reward response from the things I do. Otherwise doing things is just over for the day.

Maybe that's also why I have trouble beginning to write a one pager, but beginning to write the new Lord of the Rings is easy. The promised reward at the end is just higher. That's how I always explained that phenomenon to myself at least.
