I've learned quite a bit of lessons.
First one was when I was about 6.... Never leave your hand on the door frame when the door is about to shut.... I was distracted, talking to my friend that I left my right hand on the door frame and the door has slammed onto my fingers... resulting a broken finger.
Second one is when I was 14... Never say something that you'll regret as it may be your last word to them.... I said awful thing to mother who was sick with cancer... on the next day, she passed away, never heard me to apologize what I have said to her.
Third one was about three years ago... Never go into kitchen lights off middle of the night... I got up middle of the night to go to the kitchen to get something to drink. Somehow I knocked the glass onto the ground and while I was trying to find the switch for the light, I stepped onto big glass, resulting having to have glass pulled out of me and not walk without pain for almost two weeks.
