Michael Santarcangelo points to what can be a decisive factor in job interviews and careers:
The desire and ability to learn is important to a successful career. Actions speak louder than words, and more important than the desire is the discipline to practice learning on a regular basis.
On my first job out of college, at 22 years of age, I was assigned to a technical team and ended up sitting next to a guy in his 50s who had been a helicopter pilot in Vietnam. Bill was (and probably still is) an amazing guy; he was cool in nearly any situation, spoke ill of no one and always either had an answer or was willing to find one.
We'd often eat lunch together sitting at our desks, and I still recall a key piece of advice he shared with me one day, "Michael, the key to success in life is to keep learning. You never know it all, and the technology is always going to change. If you keep learning, you can do anything. You'll always have a job."
While I was already a passionate seeker of knowledge and experience before I met Bill, his words resonated with me then and carry with me today.
