I decided to use the tagline “make the second half the best half” because it felt like an appropriate goal for what this site is about.  I am 48 and I have been working about 20 years now (not including years in grad school).  So if I hope to live into my 90s or if I plan to work another 20 years, which I do for both, then I am currently at the half way point.  And since I plan to write about my attempts and thoughts on making that second half the best half, it felt like an appropriate tag line.  I hope it inspires you when you see it to think of ways to do exactly that for your life.
