Great insight and observations on all accounts, Don!
So true. Rumour has it that Internet Marketing is easy and a person will live the good life free from work, worry and stress.
But as you have noted, the life of the true entrepreneur is often far more demanding than a traditional 9-5 day job. As an independent business person, you are responsible for all the decisions you make and all the outcomes your efforts generate.
It is true that you can learn to work smarter, not harder, but it takes quite a learning curve and lots of effort to reach the point of high income. That is true with any business, including online businesses.
For most people, it can be a long journey, so, again as you have noted, balance is the order of the day! We should not neglect other areas of importance in our lives while trying to accelerate our marketing success.
