Regardless of who you're rooting for this Sunday, Brady's return to Super Bowl LIII isn't by chance. He continues to work on his craft and teaches us valuable career lessons that you can easily take from the field and apply to your career:

1. Train, train, and then train some more

Brady's disciple is constantly referenced because of his resilient commitment to improving, and his laser-focus on the prize. From his diet to his fitness routines to his studying of the game, he doesn't take his foot off the gas or let any distractions take him off-course. He doesn't feel like he's missing out because he loves what he does, and that gives him fulfillment. When you love what you do, you're committed to it.

2. Be a humble winner

After defeating the Kansas City Chiefs, Brady went and spoke with their QB, Patrick Mahomes, post-game. This wasn't something to get the public's attention, in fact, he'd tried to do this discreetly.

There's a certain level of respect you gain when you check your ego at the door and help those around you in the office, regardless if they're on your team or not. Regardless if they're going to buy from you or choose another service provider or product. You never know who you're going to encounter down the road, or when the tables will turn, because they will.     

3. Manage your stress

No matter the situation or amount of pressure he's under during the game, Brady can make decisions and communicate them effectively to his team under pressure. This is a skill that's hard to master and one that some of the best leaders still need to constantly work on; however, the ability to manage stress is what differentiates good leaders from great ones.

4. Be accountable

Great leaders don't take credit for their team's win, but they do accept accountability for the team's loss. Brady does that consistently, and that's what builds trust. That's what gets people to follow.

5. Be coachable

Just because Brady's considered the GOAT (Greatest Of All Time) doesn't mean he still doesn't work to improve his craft every single day - and really, every day. It also doesn't mean he stops asking for feedback (it's not like Coach Belichick would ease off regardless). Someone becomes the greatest of all time because they're constantly figuring out how to improve - whether it's asking for the feedback or reviewing their work. They're always looking for ways to get even just one percent better.

Brady isn't perfect. All great leaders aren't. However, it's how someone handles themselves, manages stress and rebounds from the mistakes that sets them apart from the pack.
