There are plenty of things out of our control. The one thing that we have absolute control over is our mindset. Once you realize that, you realize that everything in life is a choice. It is really a matter of mindset. That includes choosing happiness. When you decide how to be, you are effectively not letting anything exterior from yourself dictate how you feel. You don’t let the actions of others affect your happiness. You don’t let things that happen to you affect your well-being. Controlling our mindset will give us control over everything else.
