Whatever you do with your business, your time, your clients, you should ask yourself - does it serve my business?
It's so easy to spend time on things that really do nothing for our business. Then one day we look around and realize we've wasted a bunch of time. Unfortunately, the one things we can't afford to do is waste time.
A good habit to start is asking yourself the question whenever you think you're spinning your wheels. It's a gut check. And if the answer is 'no' just stop! It really is that simple.
