The only thing (imo) that does not interfere with someone's poker game
in some manner is listening to music while playing. Everything else, including multi-tabling, is a distraction to some degree.
Most people today suffer from some sort of ADD (Attn Deficit Disorder). The same people who must text or make calls from cell phones while driving, or any of the other dozens of things we see people doing OTHER THAN driving at the time.
I started playing live poker in '69, long before anyone ever heard the magic words ... 'online poker'. It required paying attention. There's a reason they don't let you multi-table in a casino and you only play 25-30% of the hands live per hour that you do online. I still prefer live play.
For me, the answer is, if I get bored playing. then I go do something else. If I sit down to play a large field MTT, I knew what I was getting into ... many hours of poker. That's what it's all about ... isn't it? SnG's were created for exactly the players who can't pay attention to one thing for more than 30-90 minutes.
I like going deep ... 4, 5 hours, etc. It gets more exciting the deeper I go. First, I have survived 50%, then 60, then 70 then 80% of the large field of players. THAT's when it gets exciting. I played well to get there and find the attention level at that point increases for me. For me, it's not about beating 18, 45, 90 players. In a large MTT I have to survive THOUSANDS of players.
Bring it on ... one game at a time ...
