My adventures as a sports bettor

So far they have been terrible, I started late last year and kind of seriously in February, and not counting Movie bets, I'm losing around 7k betting NBA, NCAA basketball, MLB, MMA, Box, well, almost everything. And I can't say I have been lazy, I've worked my ass trying to learn, reading books and all over the internet, comparing lines, shopping, finding arbitrages, everything, but it's just too hard. I'm about to give up on Sports, the only thing I've beaten so far is movie awards, I won around 6.5k between the Golden Globes and the Oscars. Basically I have won in the only events I have a good amount of knowledge. Following people with "knowledge" on other areas has been a disaster so far. So, until I have an amount of knowledge of baseball, basketball, MMA fighting and other sports at least comparable to my movie awards, I would be better off not betting at all. But I can't help it for now, I love sports and it's so much fun !!
