I prefer to think of the challenge we each face as relative. For example, I'm 5'8" and have er.. a LOT of weight to lose. Right now it's pretty easy for me to lose a few pounds a week, but as I get closer to my goal, that few pounds is going to represent a greater percentage of my overall fitness level.
OTOH, my mother, who's considerably shorter and smaller than I am, is already at the point where every pound represents a huge achievement to her.
My 70 pounds is not HER 70 pounds.
I've even decided not to set an overall goal weight. My big overall goal is to be at about 25% body fat. I might revise it once I get there and know how that feels.
So, I guess what I'm trying to say (in my own long-winded way) is
to the Club!
May I Join?
Just let me know. Thanks. You guys are my heros.
As mentioned, you may find it easier to break up the 70 pounds into smaller amounts. Maybe 7 lbs at a time. You can do this! 
to the board, I have nothing to add that the previous posts have put in. I have been in your postion thinking that it is such a mountain you have to climb. Like others on here I broke it down in to small achievable goals and that made it so much easier. 
I am so glad you finally decided to post!!!
