No One Learns From the Pocket of Others

Or محدش بيتعلم من جيب غيره

That was never truer than when I literally paid money to compensate for giving an un-cleared discount on an item, back when I used to work for the family company. That certainly taught me a lesson!! No more discounts without clearing them properly first. It's self evident too. I still remember it... something that happened over 10 years ago. If he had simply told me don't do that again (I mean come on, I'm the boss's daughter) I wouldn't be here talking about it now. At the time I thought he was being too tough on me, it was my first mistake. Now I know better... much better.

You have to do things yourself to remember them. Getting down to the nitty gritty is the only way to learn.
