you've touched on one of the biggest reasons that many of us don't exercise enough.
Finding the time to exercise is very difficult when we are very busy (which seems to be all the time).
I actually think the issue becomes one of priorities.
If you were to give up your business, I bet it wouldn't be long before the gap it produced in your day would be filled up by something else.
I don't think there has ever been a time when I've had the time to do everything that I've wanted to do, or needed to do.
Under these circumstances, you have to be prepared to let something go.
Because our weight is so important to our health and happiness, exercise and losing weight deserves to be among our very highest priorities.
The fact that we say that we need to "find" time for exercise assumes that it is not as high a priority as it possibly should be.
In addition to making the time, I find exercising in the morning before I go to work is perfect because it gets done more times than not (I exercise nearly everyday).
Just my two-bobs worth, hope you find it useful.
