Started flying for work approximately 3 years ago and I have to say; you million milers (or 2M,3M,4M,etc) are really really tough people.
Barely hit 500k recently and I'm feeling 'tired', especially since this year has been constant travel every week. Hopefully I'll keep up the pace and hit MM before I leave my 20s.
Major Props to you guys. Thanks for all the Flyertalk wisdom you share.
