You’re right about being tied down. There are so many opportunities out there and so much potential for personal growth that we no longer need to do things the old way. There are exceptions for those with families, but I think even then there are an incredible number of opportunities to gain independence if the work and effort are put in.
My experience with the schools in Nepal had a huge effect on me too. I think there’s no better way to improve the lives of others than to share our knowledge with them (that’s not why I was there — I was just getting a tour of the school — but that’s what became most obvious to me). This is especially true for people from developed countries going to developing countries. Our access to information gives us so much potential to share and improve the lives of others.
The key is figuring out how to best do that. 🙂
