The key ideas in The Compound Effect

Larry, Scott and Brad

Hardy imagines three friends. Larry changes nothing. Scott makes small good changes, like reading ten pages a day. Brad makes small bad ones, like buying a big new TV and watching more of it. For months they look the same. Years later the gap is enormous.

The formula

Small, smart choices, plus consistency, plus time, equals a radical difference. That's Hardy's formula. None of it looks impressive on any given day, which is why most people quit before the curve starts to bend upwards.

Track it before you fix it

You can't change what you don't notice. Hardy's first step is to carry a small notebook and write down every penny you spend, or everything you eat, for a few weeks. Simply watching tends to change what you do.

Why-power

Willpower runs out, Hardy says. A reason you care about deeply, which he calls your why-power, keeps you going once it does. He also wants you to watch your influences, meaning what you read and listen to and who you spend time with.

Lines worth underlining

  1. Small choices

    Tiny good choices, made again and again for years, add up to a huge difference.

  2. Three friends

    Three friends start out level. The one who makes tiny daily improvements ends up far ahead.

  3. Patience

    Early on the gains are too small to notice, which is why most people quit too soon.

  4. Tracking

    Write down each time you do the thing you want to change. Tracking shows you what you really do.

  5. Momentum

    A new routine is hard to start, like pushing a still merry-go-round. Once it's moving, it's easy to keep going.

A story from the book

The Thanksgiving journal

Hardy wanted to be a better husband. One Thanksgiving he started writing down something he appreciated about his wife every day, and a year later he gave her the notebook. Looking for the good all year had changed how he treated her.
