Following your guts is good. But why would you flex anyway? Showing pride in your bets is not bad also makes you known winner among  your friends. This leads to you being a target. I am not saying your friends will plot against you but they are fellow gamblers as well and in need of money.

I feel its better to keep these decisions and wins to yourself. Maybe share your losses everyday but not your wins. They might find out eventually though but I would avoid flexing.
