Example: If a person is hungry, he or she may choose to eat a salad rather than a cheeseburger because he or she wants to be slimmer.
A motivation may be intrinsic, extrinsic, or both. Intrinsic motivation is the motivation to act for the sake of the activity alone. For example, people have intrinsic motivation to write poetry if they do it simply because they enjoy it.Extrinsic motivation, on the other hand, is the motivation to act for external rewards. For example, people have extrinsic motivation to write if they do so in the hopes of getting published, being famous, or making money.

Maslow believed people pay attention to higher needs only when lower needs are satisfied.
