Need to lose 19 pounds.

To lose weight i’ll: walk every morning, and night. Jog once a week. Go to sleep at 9 pm, and wake up at 6 am. Go to the YMCA at least 4 times a week. 1 junk food a day, at most. Eat only breakfast, lunch, dinner, and 1 snack a day, at regular times. When I walk, power walk. Limit meal portions. Drink at least 4 bottles/cups of water a day. Sodas count as junk food. Will do yogo class at school.

If I break one of my rules I can’t go on the computer for 1 week. I’m addicted to the computer so it works.

Is there anything I should add?
Does it sound good?
