Outbound
One of the characteristics I have noticed amongst all of my friends who are RPT/Jet drivers is that they are all positive people who will encourage you and cheer you on.
They will do what they can to help and don't criticise or speak negatively about other people.
I suggest you think about the guys you know who ARE in the airlines and think about the common character traits amongst them. Try to enhance those traits in yourself (withou faking it). Smile. Don't be negative. Don't criticise, whinge, bitch or make excuses.
... and don't be like 160 knots
Try to get into a Sim, even the "toy" 737 sims at Darling Harbour and (?) Surfer's Paradice are beneficial (mate of mine used it before he got into Qlink and swears by it).
Good luck
