It’s always good to plan. It’s helpful to layout scenarios and figure out how you can make them work. Then, when something requires action, you’ll be prepared to execute.
However, there’s no use worrying about it. Create your plan and then leave it alone. Don’t stew over the future – it isn’t here yet, and you have right now to think about, too.
So, let go of the habit of worrying about and creating drama over events that haven’t transpired. Even if they do transpire, you have your plan. As long as you execute it to the best of your ability, you’re doing enough.
No need to worry.
