I am a lucky guy. Lucky to have lots of great people in my life (you know who you are) and lucky to have thought-provoking and touching interactions with them. Prime examples are the letters I received from my brother (yesterday) and my father (today). Both are wise beyond their years, which is saying something for my dad ;). They remind me to revisit my approach to life sometimes. That can be good to deal with less-than-stellar times, but it can also be good to shake one from an otherwise pleasant complacency.
Like I said: lucky. :)
