What I used to do that helped me be real effective.
I would work in 45 minute blocks.. with a 15 minute break.
Say I am working on 5 different things, I allocate 45 minutes to each.
Let's say I need to work on a sales script, work on a new idea, Work on B.S. Dream idea, Buy something, call my attorney, etc..
I will allocate 45 minutes for each. If it takes 5 minutes oh well, more time to knock off.. and no I do not go on to another project.
That way if it is on my list of things to do, they get done and I do not get wrapped up in one thing for a week.
So 9-945 Call the accountant
10-1045 Work on Sales Script
11-1145 Work on new Idea
2-245 Work on buying something
3-345 Work on B.S. Idea
When you are in business you have to do many different things..
