I came across a great blog post on Zen Habits about simplifying your life. The post gave 10 things you can do to make your life less cluttered.
The fifth one, simplify your to-do list, has been something I've been practicing for some time. I try to start each day thinking about what the most important things I need to get done that day. Most days I have a top 3 work list and a top 3 other list (household projects, volunteer stuff etc). I find if I focus on those things, I'm less likely to get distracted by other activities.
The other thing I like about the blog post is the advice to pick just one thing on the list and try start practicing that today. Tomorrow, pick something else on the list. Don't try to do everything at once.
Today, I'm going to clean off my desk. It gets cluttered easily when I'm traveling a lot because I throw things on it between trips and piles build up. I'm not traveling this week, so it's a good week to do a little organizing.
