Dhirubhai Ambani - You never had MBA or degree

 See, I only had 10th class education and what made me so big is I worked hard and used my brain.

I didn't learn in any big school or big college so I had no idea how the things were done in corporate world.

I took a risk and started my business, I made many mistakes and learned from them. Over the time, I improved my skills and knowledge and got to this big position.

If I could do it, you can do it too. Just need confidence and self belief.
