Anytime I have a big project I am dreading, I set a timer and work on it that amount of time. Then, if I don't want to stop, I continue. But, if I am still not enjoying the process, I stop. It helps me no matter what I am doing. Cleaning the garage is another one I use this method with. After a few timer sessions it is amazing how I get over the hump and have it almost finished. I have to admit, it really makes you feel good to have worked on it and encourages you to get it finished.
