Yeah I have been on both ends of it. It happens. Can't let that stuff get to you.
In regards to frequency it is just a matter of seeing more hands. Heck when I only played live, 2 tourneys in a day would be unusual and maybe 3 was the most I have ever done in one day. Plus the hands come out so much slower in a live tourney. Online you can easily get in dozen a day.

I truly believe that if you can't accept that these things happen, it will fundamentally change your game for the worse.
