I think I need to do this

I'm reading on these message boards how people are losing weight by lowering their calorie intake and moving more.  I know that I had said earlier that I would only exercise every other day.  Now I really think I should exercise 6 days a week.  I know it will be challenging but everybody I see that has had dramatic weight loss has done this.  I want to reach this goal so I must push myself to do this.  The thing is I'm feeling really lethargic today.  I don't feel like doing much of anything.  I still might push myself to go to the gym and just work out even if it is only for 15 minutes.  I really want to make progress in this.  I have good weight loss numbers but want a little bit better for myself. Just want to step it up a little.
