What piece of advice would you like to give to any feet pic seller?

No matter how far you get into selling feet pics, little to much experience, there’s always something to learn. What has been something you've learned that might help someone else? Tips? Stories?

Mental health? Physical health? Has selling affected you (and/or your environment) in any way? How do you handle that? Literally anything that's taught you something that you feel might help someone.

Not just advice for beginners but for everyone. Not the basic "Hydrate" advice. Even stories/experiences that show the realistic side of selling feet pics (good and bad).

ANYTHING that had an impact on you, and you feel others might learn something from, or would be good/bad to hear about.
