I am sure many of us look to our parents, grandparents, and other relatives as heroes.
For me, I look to my dad as a hero, which is kind of funny considering how often have disagreements. I'm reminded of that line from Randy Pausch's last lecture, "Just remember, when your father was your age, he was fighting the Germans." Growing up I always heard stories about what my dad was like and what he was doing when he was in college, and the stories always seemed so distant. Now, I am going through those same years, and it blows me away to think about what my dad went through when he was at the same point in my life as I am.
Coming to the US with only a few dollars in his pocket, not knowing the language, working full time at bad jobs in rough neighborhoods in Houston, going to school full time in engineering, and building a life based around making sacrifices for the benefit of his family -- comparing this to my own life, which has been free of these hardships ('cept full time school in engineering, of course!) largely due to his efforts, I can't help but be inspired.
Definitely second this, my grandfather was 98lbs wet, and the kindest person I've ever known.
Quiet, calm, assertive and wise...he's the reason I can't shake this desire to start my own business. He started a business in the 50s with minimal resources and grew it for 50 years before it was sold in 2000. I still remember him and my father paying me less than minimum wage (at the time was $5.15ish maybe?) to sweep the floors and handle trash and pick items....I miss that building, and I really wish I was older and could have talked to him more seriously before he died.
