No gut wrenching emotional comparisons required to run this routine.
Would I spend $x on pin A? if yes,
Am I ready to buy pin A? if yes,
Do I have $x? if no,
Do I have pins B and C to sell for $x? if yes,
Am I ready to sell pins B and C? if yes,
Trade B and C for A = yes
Would I buy JJPPOTC or TBL or Alien or BBBr or (insert dream theme) for $12k? yes
BTW - what do these pins have in common? They were all produced in low quantities that fell short of demand. They subsequently enjoy strong demand and high prices today.
