Hitesh Gorantla's Key Ideas from The Power of Habit
by Charles Duhigg

“That’s the rule: If you use the same cue, and provide the same reward, you can shift the routine and change the habit. Almost any behavior can be transformed if the cue and reward stay the same.”

You cannot truly extinguish bad habits. Habits are strong, and when the cue appears, your brain will always crave the reward. However, what you can do is replace the routine. The cue and the reward have to stay the same, but the routine does not.

This is called a Golden Rule. This rule has helped with treatments for alcoholism, obsessive-compulsive disorder, and hundreds of other destructive behaviors

“If you focus on changing or cultivating keystone habits, you can cause widespread shifts.”

Some habits have the power to start a chain reaction. Some habits are better than others. These habits are “keystone habits.” A keystone habit starts a process that changes everything. Success does not depend on many small things but instead relies on identifying a few priorities.

Keystone habits are like small wins. Accomplishing them is not a big deal. In fact, it’s quite easy. But this small win will drive bigger wins over time.

“This is how willpower becomes a habit: by choosing a certain behavior ahead of time, and then following that routine when an inflection point arrives.”

Willpower is the most important keystone habit for individual success. Studies show that it’s more important than IQ and other factors. People with high willpower get better grades in their classes and gain admission into more selective schools. They spend less time watching TV and more time doing homework.
