I am 54 and starting flight training and wanting to do this as a career. I’m encouraged by many pilots saying there is a pilot shortage and to go for it. I am single with no obligations.
I think you should not touch a glass cockpit for the first 200 hours, because it makes you lazy, you don't have to think. If you are going to fly professionally. There are still more steam gage aircraft than glass cockpit aircraft and steam is not going away for many years, so it's good to learn...
I love EFB's and I think that paper is so out dated and much slower and more awkward to get information from and it's not good to have you're head down in the cockpit too long.
