Sometimes small business owners have to know when to say no. This is a very useful time management skill. Sometimes there just isn’t enough time in the day for everything we want to do. Maybe you’ll have to have coffee with that potential client tomorrow. Remember you have to take care of the clients you already have. Another reason that you need to learn to say no is because you have to take care of your health. You certainly can’t make much money or do much networking if you get so sick that you wind up in a hospital. It will be hard at first, but after a while you’ll get the hang of it.
