I don’t normally use a to do list except for things where I don’t have anybody that is waiting on it. Most of my website stuff falls into that category.
I tend to check the forums first and then try and get a few quick wins out of the way so I get the ball rolling and if I don’t achieve anything else in the day, at least I have done something.
I think it would be a tough thing to spend a day on one task and then another day on another task. Much better to go with, “send a few link exchanges, write a review, add some pages etc”.
The worst thing that can happen for me is I’m trying to get something working that I’m not really sure about and it doesn’t work I normally throw the hands up in the air and look for something else to do. That’s when I normally think about doing my accounting/tax stuff as the quarterly returns come around really quickly.
Basically I think you have to make sure you keep the promises you make to yourself and work the best way you can. Up early in the morning and finish early works best for me. I guess we are lucky in that we can work when we want and goof off when we want. Just depends on the levels of income we need to keep and maintain those things that are important to us.
