Good friend of mine was a linesman for a power company. Secure job, not bad pay but something was missing. He took up flying, I used to join him on nav exercises. We had some great spur of the moment jaunts.
Fast forward 30 years, he's a senior check and training captain on 787's. He does medium haul trips to locations he enjoys.
My brother was at a loose end. I encouraged him to pursue his interest in aviation. 30 years later he's had a varied and interesting career. Now flies B777's.
Both are very happy with their lot and have no regrets.
Give it a go, if it doesn't work out nothing lost. Better than 20 years down the track thinking I wish I had..
