I've found that once I start doing anything for a living, it takes the life out of it. Once anything becomes a chore and you're no longer learning much every day, it just becomes passe'. Sailing is something I hope does not turn into a chore. We often think, "Wouldn't it be great to do that every day for a living," only to discover later that doing it for a living is not all that great.
One of my favorite stories that illustrates your point:
An elderly man lived next to middle school and had a gravel driveway and aluminum siding.
After school in the early afternoon three trouble-making boys would stand near the edge of his property and chuck pebbles at the side of the house.
Needless to say this would drive him crazy. He would come out all upset and hollaring at the boys and they would run off laughing.
Being old and wise like mr. murph he came up with a plan.
One afternoon instead of coming out screaming at the boys he called out them and said he had a proposition for them.
He explained that his doctor had told him that his afternoon naps were interfering with his sleeping at night and the boys making sure he couldn't sleep was a good thing.
So he was afraid they might get bored with pinking the stones so he wanted to pay them. He said he would give them three dollars, a dollar each day. The boys were of course delighted.
After a couple days when it was his time to pay he only gave them two dollars. He told them his social security check was cut and he really couldn't afford the extra dollar. The boys were not happy of course but figured two bucks wasn't bad.
A couple days later when it was time to pay he only gave the boys one dollar explaining that his medication costs increased and a dollar was all he could afford.
The boys were of course outraged. Only a dollar and they had to spit it three ways. It just wasn't worth it any more. They made it very clear they would not be taken advantage of that way.
The old man just smiled and thanked them for their service and promised to contact them if his finances improved.
Then he went back to finish his nap in peace.
