I am you my friend. I did the engineering thing. Ever see "office space"? I'd bet we have a lot of stories in common. And I was an engineer in ICT too....
If you are going to do it, go to a school that will get you through quickly. Seniority is everything so get your ratings as quick as possible with as much multi time as you can (such as ATP - I didn't go there though) and get on with a good regional (not someplace like mesa).
There is a ton of negativity in this profession. Most of the people have never worked in a cubicle so they won't understand where we are coming from. Every time I mention that I left engineering for flying, I get grief about it. But I don't regret leaving the big salary at all. Money isn't everything and it will come around.
Feel free to PM me with any questions!
