Im also very scared of heights, thats what keeps me on the rock. I got a job as a tower climber when i was younger and it terrified me but the money was good so i took it.
There's only 3 people i will climb with all of us are bonded through fear.
Fear is normal, the folks that dont admit it are lying.
I have a good buddy that left working where I work to do the lineman school! He is now making very good money. And he gets to travel and work outside. While I'm stuck I a factory sweating my sack off 12 hours a day 6plus days a week.
