Imagine you have the best tea in the world and you put it into a bag that's impermeable. It won't work. You just won't be able to make a cup of tea. For the teabag to work, it needs to be porous. You need the tea and the water to come in contact with each other. In our lives too, we cannot survive and thrive in isolation. Leaders need to be careful not to build walls around themselves that prevent people from reaching out to them. As a leader, you need to be able to touch other people. The tea was meant to mix with the water. Similarly all of us were designed to work with other people, with teams, and with society at large.
