I bought Pokémon cards in third grade I think it was 2003. Went all in with 100 SEK in coins! So 100 Swedish coins I brought them to school to buy I think around 50 Pokémon cards from a person that sold them. Ah in fourth grade everyone stopped to play it in my class...
So in a way a waste of money but it teached me that if you want something just go all in and get it! Fail more and fail faster is a good strategy in life to learn things fast rather than hold back! Also learned that others rather want money instead of stuff that may go up in value in the future!
