What is the most important lesson you want us to learn from you?
This like going to a pharmacy and asking, ‘What is the best medicine you can give me?’
There is not just one thing, whatever you need, you can get everything here. Why should I limit myself to one advice for everybody? If someone is leaning to left I would say, move to right, and if someone is leaning to right, I would say move to left. Be in the centre!
