three basics...
1. Swimming proficiency, to the level of a lifeguard, being able to safely dive in and save a drowning victim.
Usually, a drunk friend that "gets in over their head".
2. Dance Salsa, you don't want to be holding up the walls whilst the woman of your dreams walks by.
You have the confidence to take her hand, lead her to the dance floor, and swoon her.
3. Fight, you never know when the boyfriend, of the woman of your dreams, is watching as you make her melt on the dance floor. haha
