OK, it's one of those "it depends" questions, but here's my experience. I jump into a new table and, maybe because no-one has me figured out yet, I seem to go up maybe 50-100% of my bankroll pretty quickly, say under half an hour. Trouble is that I stick with that table for several hours more and either trickle it away or more likely make a bad call against an all-in.

Does anyone follow personal guidelines such as I quit after an hour or when I've made x% of my buy-in?

Just wondering as I've seen no guidance on this one on the site.
