When you’re very good at “n”, there are probably thousands of people who are also good at “n”. But if you are good at “n + 1”, that number is far smaller.
And if you are able to add one (+1) to the equation – it increases your ability to withstand anything that comes your way in Life.
Not only do you have the ability to withstand life’s events – when you add that +1 it increases your chances to build upon your current situation.
An example of this would be your hours getting cut at work – by having that +1 you are now able to make up for the loss and find new opportunities to expand and grow. You have now made yourself indispensable.
Indispensable not only to yourself but to any and all persons around you. With your increased skill set your hours may never be cut in the first place.
