I love learning from great entrepreneurs. One of my favourite at the moment is without a doubt @garyvee. The amount of valuable information he provides on a daily basis is impressive. Despite studying marketing and business, you only learn certain things by being a practitioner in the field.
In the pizza industry, I studied from the best pizza makers in order to achieve enough knowledge to be able to create a product that would truly represent me in my future restaurant. It is the same process, you have to learn from the best in order to progress.
I love the process of learning and then being knowledgeable about something.
This quote fits perfectly in my opinion.
