Overconfidence is an extraordinary success blocker and most people straddle the fence between believing in themselves too little and believing in themselves too much. Confidence is key to any level of success. Overconfidence is the beginning of a loss of success.
When you get overconfident, you take for granted the principles of consistency, persistency, and passion. You begin to live under the illusion that your success is all YOU and, in this way, as long as you exist, so too does your level of extraordinary success. This couldn't be farther from the truth.
Your success is built and based upon your daily thoughts, plans and actions. In the moment that you change course and stop doing the things that got you to this place, you will find that your footing begins to shift. Before you know it, you're out of the limelight, your success is waning, and you won't know why.
To you, it'll be as if nothing changed. After all, you haven't changed so why should life?
The truth is this: If you change what you give to your dream, you alter the entire dream. Don't get it twisted. This is not about "hard" work.
Hard work says "I have to work hard to get what I want and if I ever stop working hard, then I'll stop getting what I want." Extraordinary success is not a 2+2 = 4 kind of thing. It's really a 3X3 to the third power kind of thing. Your success multiplies in astronomical ways based on minimal amounts of input. You give your all in a little and there's no telling as to how it'll grow so it's not about you doing a certain amount of work to get a certain amount of result.
However, it is about you approaching ANY and ALL work with the same level of initiative, fire, passion, purpose, and planning that you did at the very beginning... and that's where most people lose out.
Fervor in the beginning of a journey is easy. It's new. The goal is new. The dream is new. It's like a shiny, new car. It even smells good but talk to me when you've been in the dream for years, when there've been good and bad times and here's where the champions are born: Champions don't get defeated by the discouraging vicissitudes of the game. In fact, it's in the tough moments that they bring their passion to the forefront because they understand that passion and purpose at all times is exactly what they need to succeed.
What am I saying here?
Confidence is key. Overconfidence is a death sentence. It's so easy to become overconfident without ever noticing until it's too late. Remember that your best cure to the overconfidence bug is to remain grateful at all times, to check your passion and purpose level at all times and to use the rough patches as opportunities to train yourself to keep doing what you know must be done in the SAME SPIRIT that you began it with.
