[RJT]

Have you tried making a list of things to do?

I find that simply writing all the things I need to get done helps in three ways.

1) It organizes my thoughts.
2) I get the worry out of my head (somewhat) and onto a piece of paper.
3) I feel like I am getting somewhere (and I am) as I scratch off the things I have finished.

I guess four ways really. 4) I accomplish what I needed to do.

p.s. The list never ends, though.
