Gambling is a grind. Sure you can go big and hit every now and then but long-term to try and be +EV, you have to grind. I enjoy the grind. Its a challenge to try and beat "the system" (not easily done).
Big hits are good short-term "gratification" but I don't feel like I actually beat the system when I hit them. I think, "maybe i just got lucky". Feeling good about being lucky is nice but feeling good about being long-term + money is much better.
