Age is just a number. 55, 42, 30, I don't care as long as you have a spark and sense of humor. If that makes me a pervert, then you probably are too curmudgeonly, boring, and righteous for me.
Employed, responsible, can tie my own shoes, change a tire, replace the power source in a computer, change the oil in a '66 Ford, replace a faucet, hit a high draw, stop a penalty kick, curse in Spanish, hold my own against a 9 year old playing Halo, smile in spite of it, do a cartwheel, run 4 miles (all at once), belch my full name, sing the entire 2nd movement to Beethoven's 9th Symphony, and figure out the Jumble words faster than most. Basically, the entire package.
And as far as ambition goes, I can be tremendously ambitious if it's something worth being tremendously ambitious about. I do not run willy-nilly, full-ambitious after anything simply to be willy-nilly, full-ambitious. That seems indiscriminate and dumb.
What do you got?
