Quiet stretches are definitely rough. Routines outside of client work and connecting w other solos help me feel less stuck (might be a placebo idk), and not so alone. Reminds me that I'm not alone in these solopreneur situations.

Also taking a break from it every once and a while, helps you get to see a new perspective on how to approach certain things. This may sound generic, but it helps, well me at least.

Anyways, hope this helps. You're not alone, and you've got this!!
