In my last progress update, I promised to let you in on a couple of things that have turned my well-being around in the last couple of months.  I alluded to sleep being one of them.  This is one of the few times I’m touching on something much larger than golf, so hang in there because I think this is important. Without a doubt, sleep is the fundamental building block of everything we do.  It’s a fundamental human requirement along with food and water.  You can eat poorly or not get adequate water and probably get by for a long while.  If you don’t sleep properly, though, life becomes a mess. Let me give you an accounting of my last 5-10 years. I’m a software engineer so being able to concentrate is kind of important.  Several years ago, I noticed that I was having trouble concentrating at work.  I was having trouble getting to work before 10:00 or even 11:00 in the morning.  I didn’t really feel rested in the morning when I woke up.
