Before you invest your time to help someone, fix their problem, or give them helpful advice, make sure they actually need and want your help.
Because you might end up robbing them of an opportunity to experience something and learn through doing. Or worse, you might end up wasting your time because they have already solved the problem.
Offer help, sure, but don’t just give it away unless you’re sure it’s needed.
Hat-tip to my exquisite wife Szeréna for always pointing me in the right direction.
