Life is complicated. There are so many things we need to tend to. And Sigmund Freud understood this in simpler (or more complex) terms.
In talking of the psyche of people used the terms id, ego and superego. Basically, the id is what you want (your desires, wants and needs). The superego is what is expected and demanded of you from society. And the ego is what you do when taking into consideration of the superego (pressures from society and culture) and the id (your personal urges). These three need to be balanced for a person’s well-being.
