My "drive" to paper chase has changed a lot since I started DX-ing in 2001:
1) Started out wanting to get to Honor Roll. Made 1 Q per band, and 1 Q for "insurance" (pre-online logs)
2) Decided learning about 5 different bands and building antennas for each was a notable goal
3) Expanded 5BDXCC to 8BDXCC
4) Decided DXCC Challenge was something to do so I wouldn't get terribly bored waiting for the next ATNO activation
5) Decided 160M was an insane but _maybe_ do-able goal. 80M was hard enough - hi hi, but what the heck . . .
6) Got addicted to 160M
7) Made HR Mixed - started thinking about HR #1, but with an entirely different attitude than with regular HR . . .
Dropping the DXCC Challenge - just no longer interests me - but might check off a bingo slot every now and then just for laughs
9) Stay on the HR - by working ATNO's
This process has led me to concentrating heavily on 4 bands - 160, 40, 30 and 20M, with really good mono band antennas on 40 and 20M. I can understand the guy who just lives for 20M - although for me - one "day time" band and one "night time" band - but pull out all the stops and put up some serious aluminum for those two bands excites me more than being mediocre on 160 - 10M - which used to be my story.
So - the antennas drove the DX - or did the DX drive the antennas? My wife thinks I DX to have an excuse to build antennas. Hmmmmm.
