There are a couple disadvantages in being your own boss: nailing down a schedule that works for you, and then sticking to it, and being self-disciplined enough to ignore distractions. These can be managed, but it takes some tweaking.
I tried, oh how I tried, to force myself into a "regular person" schedule--go to bed at 10 or 11pm, get up around 7am. It worked for a while, but my brain does not kickstart very quickly in the morning, so I was seeing less than optimal productivity and would often end up staying up late anyway to play catch up. I've finally been forced to submit to my natural arcadian rhythm which has always been of the night owl variety. So I sit in the quiet of the wee hours and plug away, because it seems to be the only time I can truly focus.
Self-motivation is a dragon which must repeatedly be slain. Oh sure, there are deadlines to be met and bills to be paid which serve as continual kicks in the pants. However they aren't always enough to coax my brain into "on" mode. I'm not an organized person by nature, but if I force myself to organize my goals and priorities, it does make the desk a bit more inviting place to be.
Lists - these are a *must*; I normally do them on paper so that they're right in my face either next to my computer or on the bulletin board. I have lists of ideas, lists of titles and their due dates, lists of pictures that I need, etc., and then cross them off as I go.
I also keep Word open all the time. When I sit down to check email or surf the net and see a project minimized on the task bar, I'll usually bring it up and make a little progress. This makes the long evening work hours less daunting because I have a good start.
I find that getting up and moving around a few times during the work hours keeps me energized and helps prevent that pesky "desk coma" problem. These are my random thoughts for the moment. I'm sure more will occur to me at 4am, and I might even get around to blogging them. Life is good - be happy!
