Don't weigh and measure yourself constantly, UNLESS you're really serious about changing the shape and condition of your body.

Transforming the body is usually about transforming the mindset as well. Some people weigh themselves often, and get discouraged and quit often. The trick is to change the way you're looking at it. A sculptor looks at a block of stone, but while he's looking at it he sees what lies beneath. Use the bathroom scale, bodyfat measuring calipers, and measuring tape to chart your progress. Be honest about where you're at, but focus on where you're going, and how awesome you'll feel when you get there. Also, allow yourself to enjoy the journey. Be happy with where you are, because if you think you can't be happy until you've reached your goal then chances are you're never going to be happy.
