What i want to DO vs BE

What I want to BE in life is a good party chef. A great baker, i want to bake amazing cakes that people can afford and want to take home to parties instead of baking there own. What I want to DO is  make people smile and happy with my work and what i give them. i think these things are connected coincidentally. i think that in  different circumstance they could disconnect. For instance, i want to donate or give left over food to homeless people, but that won't make them happy, or smile. it might, but thats really out of my control. Which would mean that what i want to DO and what i want to BE have nothing to do with each other. I mostly believe under most circumstances that there are very connected, by example. Say you want to be a doctor, and what you want to do is make people healthy. maybe its more complex then that, but thats all that crosses my mind.
