When you do something right, you want it to happen again.
The rewards for doing something right in your business include employees being happy and customers being happy - which in turn delivers more profit and makes you as a business leader more happy.
The feeling of achieving the right things builds positive reinforcement to do more of the same. Celebrating those moments when individuals or your team achieves the right thing builds a culture of success and happiness.
Equally you need to find ways to motivate the right behaviour from those not doing the right thing. Think of it like giving your child an allowance when they do their chores, or losing weight when you stick to your workout plan and diet, or when you reward your dog for good behaviour.
