Or rather, don’t sweat or get stressed over the things you can’t control. Yesterday I was on a call with a client. He is very hard on himself in general. This time it has to do with billing his clients and getting paid. This is the first big client he has brought in himself and he is very stressed out abou the client paying. I suggested to him that he did the work, he billed the client, now it is really out of his hands. He has enough stress to deal with and doesn’t need to add this to it. Yes he is following up with the client because that is still within his control. Whether they pay or not, is not.
