Maslow’s Growth Motivation Theory is based on the idea that human needs exist as a hierarchy:

• Physiological needs – food, drink, shelter
• Safety needs – protection from danger
• Social needs – love, affection, acceptance
• Esteem needs – to have high self-esteem and respect from others
• ‘Self actualisation’ needs – to fulfil our own potential

This theory has received much criticism in recent years, but I think it is still worthy of consideration when thinking about motivation problems.
