The FreeBSD question list is your friend in learning.
I have been learning FreeBSD since 2.8 I think it was, I was born in
1941 and continue to learn. I am still employed as well. Most people
on the list are more knowlegable than you'll find anywhere else and
willing to share.I took time to visit a computer group on the Greek
Island of Crete a few years ago and found that to be true face to face
You will do fine with suggestions and help from the List.
