Mathematical tyranny

I keep on having to tell myself that this whole weight loss thing is not a matter that can be mathematically predicted. That previous results do not predict future success. I catch myself thinking in the shower what weight I might be in a month or six months or a year. Pondering my decreasing fat rolls. Idle speculation, sure, but I must be vigilant against setting myself up for disappointment. Because down that path lies discouragement and resignation. And that's not the road I want to take.
