Just a thought: the difference between persistence and stubbornness is whether you get it done in the end. If you succeed eventually, your persistence paid off. If you don’t, you might be just another stubborn fool.
I was taught one trick to guarantee a win when playing games of 50% chance in casinos. Always double your bet after losing, so that your win will cover your previous losses. If you have bet $10 previously, and lost, bet $20 in the next round. If you then win $20, it will more than cover your initial $10 loss. The trick is to be sure you have enough money to keep increasing your bet, which rapidly increases to $5120 by the 10th try.
If you keep losing after 10 tries, should you continue (and hopefully have your persistence pay off) or should you give up and not be a victim of your own stubbornness?
