Few things can motivate you and dispel fear like having a plan. Even if the plan doesn’t work as expected, it gives you a framework from which you can adjust and react. By taking the guesswork out of an uncertain situation, anxiety will decrease and confidence will increase. Providence will move to assist you because you have done your best to determine a course of action and committed yourself to it.
Set a goal. Plan the work. Work the plan. Adjust when necessary. Achieve your goal.
