The mentor-mentee relationship is ideally like that of the guru and disciple: motivated by the desire of the guru to impart knowledge to the disciple.

Most successful entrepreneurs share their knowledge as a way of giving back. They do not demand compensation. Those who do are usually trying to take advantage of you.

When my generation grew up, our only sources of knowledge were books, teachers, parents and friends. The encyclopedia was an item of luxury. We faced big limits in what we could learn, where we could be and who we could reach.

The truth is that entrepreneurship is more like a roller coaster ride than a cruise.

Entrepreneurship is like a computer game in which you have to master every level before achieving success. Startups repeatedly stumble and have to go back to the drawing board. The best way to skip some levels and to increase the odds of survival is to learn from others who have already played the game.
