Well if you are serious about becoming a commercial pilot, get your class 1 medical booked. You're career won't get off the ground, excuse the pun, if you can't get a medical.
Secondly, research, research, research. Read the forums, talk to people. Plenty of pilots have channels on YouTube these days, so check that out!
Take the negativity with a big pinch of salt. No airline is perfect and there are a lot of greedy executives at the top like any industry, but life isn't half as bad as a pilot as many would have you believe.
Take a few trial lessons, see if you like!
