Not really a story of a comeback but growing up in communist Russia the battles were all about surviving the day to day basics: getting food/clothes, taking care of family members, but most importantly not having any chance to do anything creative or work on something and knowing that there will be some sort of return.
Experiencing this early on in life definitely made me a lot more appreciative of all the opportunity one has growing up in a country like the US. Opportunity to be able to do whatever you want, learn whatever you like, live however you want...
