Thanks, MO. I'm not sure if Gordon is going to give me a habitat column or not. I tried getting a hold of him a couple weeks ago, but missed him. I'm planning on following up this week.
As for the second question, I'm no doubt I'm preaching to the choir when I say you never work harder than when you work for yourself. You just find a way to make the time. That said, it sure helps a ton when your passion is your job, as it serves both in providing the income of normal jobs, while also satisfies the cravings for time spent on hobbies and/or "fun time." Sure, my normal work days are 12-16 hrs and I work every weekend my wife is stuck on a weekend shift (every other week) and more than I should when she's off, but most of my days are filled at least a few hrs of things I'd want to do on "days off" anyway. So, at least parts of many days feel like "play time" not "work time," and that makes it more than tolerable. Heck, there are many weeks when all the "work" I do seems like "play time." When you'd be willing to pay to do things you're being paid for it makes it real easy to be a workaholic.
That said, something I've been struggling with the past couple years is taking on too much and having literally no time left over. It's been an interesting transition for me. For something north of 20 years, it was constantly scrounging for more and more work, all out of fear that I'd run out of work. Somewhere along the line, that very legit concern stopped being an issue, but it took me a while to realize it and it's generally against my nature to turn down paying jobs. Long way of saying, I'm still trying to find some sort of a balance.
