My friend just quote this one. I think he is right
Day trading is like having sex.
''Get in and out as much and as fast as possible to get satisfied maximally.''
I think this exactly explains day trading. I am a day trader myself. I rather get in and out of the market 50-100 times a day and take small profits with smaller amounts of my balance than trying to chase a couple percent in 1 trade.
There are lot of comparison you are going to give, and yet SEX was your example.

Though, I felt its true. Particularly, when the market in on pump stage we as a traders are really happy
and satisfied with it due to we gain a lot of it. Then when the market is down, we are not satisfy or happy because
didn't meet the satisfaction we are aiming for it.
