1) Only you could know why you want to become an airline pilot!!! I don't wish to become an airline pilot and therefore cannot help in this respect!
2) If you're 28, I'm assuming that you have a job. How do your current job skills transfer to aviation? Team work, managerial, dealing with the public, training and mentoring, organisational etc etc. Motivation - what ambitions have you achieved in life? Do you already hold a PPL for example? Have you strived towards a qualification in another field? What experience do you already have of commercial aviation?
I hope some of these might help.
Cheers

...oh... and this may sound obvious ... but get someone competent to check the spelling, syntax and grammar!!!!
