Great idea to forget the number on the scales. There are too many factors that play their part for it to be meaningful. Sometimes the weight loss just slows down. Don't worry about it. Your metabolism just needs to catch up on you. Don't let it discourage you it sounds like you're doing everything right.
A training partner is really helpful. The best way to find one is by joining a fitness class. You will meet like-minded people who need somebody to motivate them just as much as you do. Surround yourself with the people who will motivate you.
Unfortunately I live in a very small village 50 miles from the closest gym. I have managed to keep myself motivated for almost four years now watching videos on Youtube and constantly changing my programs. I haven't missed many workouts. I keep them to two weeks each and eventhough I hate to admit it I keep in mind how women look at me and how they react toward me when they meet me. I shouldn't beat myself up because at 53 years old I can still easily fit into a pair of 30 inch waist jeans and turn teenage heads. LOL. I think my biggest problem is I never seem to get enough sleep.
