I saw something inspirational today on BART. A man, probabably in his 40s, a plumber, painter, or construction worker of some type, based on his attire, hands/fingernails and accompanying toolbox, was intensely studying algebra on BART. He had a small notepad on one hand, a huge algebra textbook on his lap, and was solving equations one after another. He was concentrating hard, and never looked up once.
Maybe he's studying to tutor his kids, maybe it's just for personal reasons to prove to himself that he can tackle any obstacle, or maybe he's studying to complete his high school degree, whatever the reason may be, I have a ton of respect for what he's doing!!
