The problem is that, growing up (in case $10 is a small thing to us today), we forgot how as children we spent whole weeks, and maybe even months, almost without a single dollar, playing with friends on the street or somewhere in nature.
How much money do you need to go on a trip to a forest, under a tent, with your friends and teenagers on Saturday morning? by a lake or river with fishing poles and a ball, with three muffins and a can of pate, on which you can spend two days, until Sunday afternoon?
I bet that 30 years ago I could have done something like that with $2 or $3..
And today, when I am a slave to habits and have some different desires and needs, I need 10 times more.
