I have unending enthusiasm and confidence!

Enthusiasm ends. That's what it's for — fuel for starting, not for continuing, and any January gym floor will show you the arithmetic by the second week of March.

Confidence works differently. It's assembled from evidence, which means it can only arrive after you've done something unimpressive several times.

So don't spend today trying to feel more. Do the thing at the current, unglamorous level of interest you have. Enthusiasm returns in waves you can't schedule. Structure is what carries you between them.
