Taking responsibility is like helping someone with a heavy load. You have to hold up your end of the deal. Once the load is up and moving, letting go is not an option.
Now, equate that with the running of an organization or business. Especially when half the weight depends on you but the whole load will not move smoothly without you. You are not that indispensable after all.So, make sure you have the strength to handle your end of the load before you take that responsibility.
