If you want to change attitudes, start with a change in behavior.

The quote “If you want to change attitudes, start with a change in behavior” is attributed to William Glasser, an American psychiatrist and founder of Choice Theory and Reality Therapy. Glasser’s work emphasized personal responsibility and the idea that individuals have control over their actions, even if not over their emotions. This quote captures a central principle in his approach: that behavior often drives attitude, rather than the other way around.

Traditionally, it’s believed that attitudes influence how we behave—if you feel positively about something, you’ll act accordingly. However, Glasser flipped this view by suggesting that acting differently can actually reshape one’s mindset. For example, by choosing to be kind or productive, even when one doesn’t feel like it, a person can begin to internalize those behaviors and eventually develop a more positive attitude.

This idea is grounded in psychological practice, especially in cognitive-behavioral approaches that show how changing actions can lead to shifts in thinking and feeling. Glasser believed that focusing too much on feelings could lead to passivity, while emphasizing choice and action empowers individuals to take charge of their mental and emotional health.

Ultimately, Glasser’s quote serves as a practical guide: to influence lasting change—whether in oneself or others—it is often more effective to begin with visible actions. As new habits are formed, they lay the groundwork for new attitudes, reinforcing the cycle of personal growth and transformation.
