I don't like to involve money with friends and family because I believe those two are bad combo and it can ruin the relationship over some silly things.
Well I agree with that that is why I just do that for some other activity together in exchange, like go to have a meal together, at the end when I get out with my friends usually we have fun and we don't matter if today one of us pay, we know that the other is going to pay.
In any case there is no rush to ask the payback right if you see that they aren't going to make it, then is better not to ask, at the end if you already fulfill the challenge it is still a win for you.
Gambling itself is a waste of time and money but when it comes to betting on self-improvement this can actually propel you to improve the quality of your life. As responsible people you guys wouldn't bet an outrageous amount of money
Agree 100% with that last one
Update me, OP, if you have managed to start this. Make it a great bet!
Well even if i really like to read, i never did bets on that because it is not something really measurable, i prefer it on physical things. I just mentioned it as an example.
