Created a complex spreadsheet to strategically plan my fantasy Premier League team + transfer usage throughout the season to ensure the most efficient use of top team players against shitty teams. First prize is only £100, but it's bragging rights at work dammit.
I won the World Cup fantasy league for £90 with something similar, but less complex (finished top 0.1% overall in the McDonald's world league).
Sometimes, I watch chess videos on YouTube.
you mean hipsterOh, I just realized I never mentioned that I started collecting vinyl last year and have now sunk probably close to $2,000 into my record collection. Nerdy, or just plain foolhardy?
