Each new day teaches us new things whether we realize it, or not. This process is mostly unconscious that is why we are mostly unaware. In order to develop our passion for it, we should learn how to ask questions, once we have learnt that, we should try and give them an answer, once we know the answer we should teach others. The infinite satisfaction you get makes your passion for learning grow bigger and doing it repeatedly makes you grow, and grow wiser.
