I just looked at my lifetime graph and my first 35k hands (almost half my total to date) were basically breakeven. If I hadn't luckboxed a big tourney win and cleared a lot in bonuses, I might have quit.

I agree with swigs that it won't be one big light, it will be a lot of little ones. Make sure you're reviewing your sessions and posting the difficult hands here. Early on that helped me as much as anything I think.
