Training, sleep, and contentment

I've planned and logged every meal since September 5th. I'm making sure I get the proper amount of protein, fat, and carbs daily to make gains. That's a little over 2 months. I've lost 30 pounds. I'm feeling stronger, faster, and I've built up more endurance. My endurance has been the slowest to build, but it's still getting better. For the first time in 11 years I'm getting enough sleep. I feel really good right now. By God!?! Is that feeling happiness and contentment? Yup, I think it is. I think I could get used to this.
