Now here is a topic near and dear to my heart! 
I come from a family where everyone until recently lived within a 10 minute radisu of each other. I am talking about 16 grandchildren, 6 children, great-grandchildren, grandparents. ETc. Phew! No one moved out of Rhode Island, much less go hiking for five mos at a time!
When I did the AT everyone was quite happy for me. The local paper did a write up. All my relatives bragged about it and could tell they were proud.
Then I moved to Colorado. Might as well have moved to Mars.
Did I mention everyone lived within ten minutes of each other? It was very radical notion for my family. Made me a bit of a blacksheep in the family. 
When I quit my “good job” to go hiking on the PCT in 2002, the family was confused. (When I say family, I mean everyone. Not just Mom, Dad, brothers, etc.) Giving up a “good job” to go hiking!!! OK…you moved to Colorado away from all of us. But you found a “good job”. Time to settle down, meet a nice girl, get married…have kids! Mind you, I was only 28 when I did the PCT. When I attended a family wedding after doing the PCT, my grandmother and mother pulled me aside and asked “Don’t you think it is time to settle down?”
Two years later the wanderlust has not abated. At thirty years old and not married in my family, well, it is a minor scandal.
To go hiking instead of wanting to raise a family, work for all but two weeks a year…does not make sense to them. You should see their reaction when I spend holidays (with friends) in say Utah!
Guess I am trying to say is that many people do not understand the life we have chosen. It is a common story.
You have to do what makes you happy. For now it is hiking. In the future it may be other challenges.
I’ll leave you with these words:
Carefully observe the way your heart draws you and then choose that way with all your strength. --Hasidic saying
ps. On antoher thread we’ll discuss girlfriends who think the outdoors should be more hobby, less lifestyle…
