Starting a Fat Loss Exercise Routine

I am going to be starting a fat loss exercise routine and I could use some advice. I really am going to need some help finding ways to keep motivated and not skip my exercising for any little excuse. This has happened in the past, so I know that it is a problem with me. What do you do in order to keep yourself active? I think I am going to start a reward chart for myself so that when I am consistent I get some sort of treat. Maybe I can get a new exercise video or a new workout outfit.
