Best knowledge in the world is what we have experienced in our life. Most of us think experience and knowledge are different, actually this is not correct. Experience is also one kind of knowledge that can connect knowledge.
Knowledge without experience is like a brick without cement. If you want to build wall you have to mix both cement and brick. The wall built without cement won’t be strong.
Past experiences helps us in gaining more knowledge. It also forces us to think in a specific way, and think creatively and collect ideas. Experience can act as good base for establishing our knowledge and hence it is the best knowledge in the world.
