Holding a hot kettle not by its handle, will teach you to hold it by its the next time.
Crashing your parents car when you are semi high will teach you, never drink and drive ever again.
Failling your exam, will teach you to study harder for future exams.
Making so many mistakes, in relationships with the opposite sex, will teach you to back off until you know you are totally ready.
Being mistreated by people whom you call friends, will teach you not to go near them, but to avoid them at all costs.
Failure to forge whatever it is that needs to be made, will teach you, sometimes, to never ever try again.

However unfortunate it is sometimes, it's hard to fight against the tides of fate, which seems to have the upper hand in everything. No luck, no love, no cash - really can make one's life very very frustrating.

Luckily, I don't gamble or am in a relationship. Phew.

Sometimes, I'm amazed at how so many people have so much energy to fight on. If it were me? I'd give up. Hey. Better to prevent then to go through hurt, no ?
