Good to know
- Every lesson is someone’s own. Each square is one person’s experience, in their own words.
- Lessons may overlap. Lots of people learn the same things the hard way, so you’ll see similar or even repeated lessons. That’s part of the picture, and it shows which lessons matter most.
- Short and personal works best. One sentence about something you learned yourself. No ads, emails or phone numbers.
- Reviewed before it appears. We take a quick look at every lesson to keep the wall friendly, so yours may take a little while to light up.
- Anonymous by default. Your first name, city, and website name only show if you choose to add them.
- Changed your mind? Contact us and we’ll remove your lesson.
