Nick Saban, Alabama football coach and the G.O.A.T. of college football, is known for drilling a mantra into his team: "Don't practice until you get it right." Practice until you can't get it wrong.

He's utilizing a psychological concept known as the self-efficacy theory. Self-efficacy is a person's belief in their ability to carry out an action, or in other words, their self-confidence.

To build confidence, there are four primary pillars: performance accomplishments, vicarious experience, verbal persuasion, and physiological information.

Performance accomplishments can simply be having success in practice. So in sales, this can be as simple as practicing your scripts, nailing them, and being confident that you'll know exactly what to say when the time comes.

Vicarious experience is related to building self-confidence through what you observe. That would be seeing others on your team sign clients and close deals using the same exact scripts and frameworks that you practice, proving to you that it works.

Verbal persuasion comes from your leadership or from those around you. We all need a hype man or woman, someone who can be a positive voice in our corner and give us feedback on where we can improve.

Physiological information simply means your physical and emotional state when you take care of your body, get enough sleep, eat the right things, stay active, and feed your brain positivity rather than negativity. You create an environment within yourself where you can feel confident in your ability to do whatever it is you're trying to do, whether that's scoring a game-winning touchdown or closing a big sale.

Bringing this back full circle, instead of practicing until you get it right, practice until you know it so well that you can't get it wrong, and you drive home pillar number one: performance accomplishments. This simply means when it's game time, whatever your game is, you'll be confident because you put in the work, and you'll be ready to get the job done.
