Most of us admire the great explorers like Columbus, Lewis & Clark, and Francis Drake just to name a few.  Very few of us realize that we are all explorers in a sense.  
    We are all born into a strange world we know nothing about.  We start exploring that world within minutes of being born.  We continue exploring it to various degrees until we are adults.  Unfortunately, at some point we usually reach a place we are comfortable with and stop our exploring.  We get comfortable in our social life, in our jobs or professions, we get comfortable with our friends and decide to just stop exploring.  
    I've known people in good paying professions who loose their job because they don't want to learn new technologies or new job skills.  I've known people who ended up unemployed because they were in a dying profession and didn't want to learn a new one, and I'm not talking about this year when so many are loosing jobs because the current economy.
    As a spiritual person, I think the saddest cases of this are the people who have become comfortable with a church or belief system and never explore anything else.  They have been in the same  church since their parents brought them when they were infants.  But if you ask them why they think this church is better than another they can't answer.  If you ask them what other spiritual paths, or spiritual schools they have investigated, they answer is often "none".   This, I think, is very unfortunate when it is clear to most of us that we are living in the "End Times" and a spiritual awakening is the only thing that can save us.
