Life is funny.
When you are an adolescent with hormones raging, all you can think about is finding a mate.
No one is interested much at that point as you don’t have much to offer.
So you buckle down and work hard and build yourself into a better person.
And you work and you work and you work.
Eventually you may find yourself focused on work over finding a mate (or if you have one, spending time with that person).
Behavioral training is extremely powerful even on us humans who may see ourselves as above that.
