Does lower order needs need to be filled to get higher order needs?

Yes, according to Maslow's Hierarchy of Needs, lower-order needs such as physiological and safety needs must be satisfied before individuals can effectively pursue higher-order needs like love, esteem, and self-actualization. This framework suggests that unmet basic needs can hinder personal development and fulfillment. However, the process is not strictly linear, as individuals may simultaneously address needs from different levels depending on their circumstances.
