Let small mistakes go without stepping in
Letting a small mistake go means noticing it, deciding it is not serious, and choosing not to swoop in and fix it yourself. It is one of the hardest habits for a founder to build, because fixing things fast usually comes naturally and feels responsible.
Every time you rescue a small mistake the moment it happens, you send a quiet message that people cannot be trusted to handle things without you watching. Over time that message sticks, and your team stops trying to catch their own errors because they know you will catch them first. I have to sit on my hands for this one, honestly, because my instinct is always to fix the small thing the second I see it.
Try this today: the next time you spot a small mistake that will not cause real harm, wait and see if the person notices and fixes it themselves before you say anything. If they do, say nothing at all and let it be a quiet win for them.
