Simple, did you find the "Higher or Lower Number Game" fun as a kid? and did you try many unique strategies before settling on an optimal solution... It may sound silly, but this will generally forecast if people will stay with the hobby.<p>Similarly, Engineers were the kids that constantly destroyed their toys with magnifying glasses and illegal fireworks. This is why society must keep them preoccupied on beneficial projects, and spicy BBQ meat to attenuate their true nature. You can test folks by placing 3 Liquorice jelly beans on a pile of vanilla beans, They will try to covertly remove the defective beans at any cost, and this compulsion continues into adulthood. If this imaginary jar of beans still concerns you, than you likely should have been an engineer.<p>Have a wonderful day, =)
