I've been trying to be more productive by taking small, concrete steps. What systems have you set up for yourself?
Here's what I have.
1. Whiteboard tasks for the week, w. daily assignments
2. Check emails once an hour
3. Set default page in FF as a blank page(as opposed to Gmail, Reader, etc.)
4. Tea, not coffee. Cup of water on hand at all times.
5. 7 pull ups each time I use the bathroom.
Equipment-wise, multiple screens tend to help. A good chair too.
For the last 2 days, I've been writing a model configurator that explodes input parameters into individual objects. I probably have 8 or 9 things dependent on this (not really sure yet), so I plug away until done. Then I'll figure out the new only thing on my list.
I've tried every conceivable "productivity hack" and nothing has worked as well as this. I have scratch pads, paper on the wall, 20 colors of markers, and all kinds of automated tools for scheduling and planning. I've varied my diet, my exercise routine, my daily routine, and almost anything else I could vary, and none of it really mattered. All it ever really did was take focus away from the real task at hand.
Just identify your critical path, remove it, and repeat forever.
I started with this and fine tuned what worked for me:
