In order to gain the climate future that you want, envision yourself or your children living in it. Then courageously pursue it.
Creative visualization is an especially useful tool for creating confidence. If you can visualize yourself succeeding before attempting a task, you are far more likely to achieve your goal. Athletes visualize scoring a goal before they go out on the field, and actors visualize receiving a standing ovation before going out on stage. Even if you are just planning to out someone out on a date, visualizing a favorable response can increase your confidence tremendously.
