QuickRead presents a summary of "Atomic Habits" by James Clear:

Learn about the easy and proven way to build good habits and break the bad ones.

What's a habit? If someone were to ask you about your daily habits, you might need some time to think about them. That's because a habit, by definition, is an act that you perform automatically by instinct. Like when you walk into a dark room, you instinctively turn on a light switch, right? Habits are actions you don't even have to think about, which is why you might not realize how a small daily action can have a powerful effect on your life. If you're saving a dollar a day or smoking a cigarette a day, these actions may not seem like much now, but twenty years from now, those habits can either make you rich or, unfortunately, kill you. That's why it's important to understand how habits are formed, so you can learn how to kick the bad habits, implement the healthy ones, and take back control of your life.
