For an amount as small as $2, what would be that one thing that has been bugging you so much that you really wish there was a well designed solution for.
I can buy two pair of reading glasses at DollarTree for $2. They work. Ergo, they are well designed.<p>And two pair means I can still find a pair of reading glasses when the other pair is pushed up to my forehead.<p>If I have to invest more mental energy than walking into DollarTree, that's a bigger problem than the two dollar problem.<p>Find problems that are worth $10,000.<p>You only need 0.02% as many customers to make your nut. And the problem is big enough that people will be happy to pay.<p>Good luck.
If anything bugs me greatly, then I whip up a solution that works for me. I apply this process not only in the field of computers, but also in the workshop, the garden and our home. That's what engineers do!
