Maslow's hierarchy of needs
More basic needs have to be fulfilled for high needs to be possible.
Physiological needs: Biological requirements for human survival (e.g. food, shelter)
Safety needs: these include personal and financial security, health, and well-being
Belonging and love needs: Emotional needs for relationships, connectedness and being part of a group.
Self-esteem needs: Self-worth, accomplishment and respect.
Self-actualisation: The innate tendency to reach your potential, the desire to become everything your are capable of.
