Footballmaxxing is the best way to make friends, if you don't footballmaxx you won't have much friends unless you have another niche talent that you can put to good use.
I noticed in High School the kids with the most clout were footballmaxxed, this applied for everyone not only if you were ethnic, if you wanted to get popular in High School, just get good at football. Other ways you could be popular is being smart academically but that only works for the top 10-20% of the grade, otherwise you have to resort to footballmaxxing. I was decent at football but was still treated like garbage because I hated talking to the normgroids there and their stupid discussions which didn't make sense to me so I never made much friends.
Cricketmaxxing works too if you're curry.
