I've been talking a lot with my fiancee lately about tricks one can use on themselves to make the week more productive. For example, I usually throw away many of the vegetables I buy; typically I just don't get around to eating them. Something of a solution: now when I buy vegetables, I immediately chop them up according to how I use them (in this case, I make a few salads in tupperware), such that the food is ready to go when I need it during the week. Another example: my oatmeal was in a heavy, industrial size Quaker box on the top shelf (which itself contained large bags), such that there's a slight amount of effort required to make oatmeal each morning. This had meant that I'm eating other less healthy things for breakfast. Simple solution: buy some plastic containers with a lid to hold oatmeal and put em within easy reach. Every second counts when bussing it to work at 7am.
You also have to make these sorts of behaviors automatic. When I get up on Saturday, start the wash immediately. When I buy groceries, make lunches and slice vegetables for the week. When I get to work, don't check email or blogs, start a small project immediately. Making these decisions daily, even if they're small, requires some amount of effort. The more we automate the more productive and happier we are.
Ramit Sethi, from I Will Teach You to be Rich, has a great NY Times article on how to overcome these small behavioral hurdles that are keeping us from being rich, fit, and organized.
