If its what you really want to do then dont give up on it. Just do your best not to get dragged down in debt in the process. Eventually there will be a shortage of pilots in this industry. This industry was looking a massive retirements in the near term until they changed the age 60 rule.

Many of us where working on our ratings or instructing when 9/11 happened and we could have quit then as the industry tanked but looking back it was a great time for people to be working on ratings or instructing because airlines weren't hiring. When airlines aren't hiring you aren't losing out on potential seniority that others would be getting. By the time you get qualified and start looking for a job the industry should have cycled and start recovering.

Now there are alot of factors that can change any of this but that goes with everything in life. Good luck
