The right thing to focus on is always the thing we can control. When we complain less, we have more time to do. Complaining is a form of comparison, which is the #1 thief of joy. When we complain we are focused on the wrong things. Complaining is usually focused on the actions of others. Since we cannot control others, complaining is more than useless, it steals productivity and happiness. We should only focus on the actions we take. When we focus on our own actions, we will be more successful, we will be happier, we will feel more satisfied.
