I hate to say it, or too sound in anyway insensitive or arrogant, but the way forward is pure hard work and determination.
Remember the old saying? ''the harder I work, the luckier I get'' and that is what it boils down too.
Door knock, get in front of people, be that person they think of, yes you are a little bit older, but you are also wiser, more experienced in life and I would assume that you have a more mature outlook.
Airline flying for most of us is more of a job now than a vocation (I fly a glider now when I want to actually fly) so set your sights where you think you can achieve a good income and as suitable lifestyle for you and your nearest and dearest.
Most importantly...remain focused, remain committed, and remain enthusiastic.
