Thomas Edison failed 9,999 times prior to unlocking the secret of the filament inside the light bulb. Why bother with the 10,000th attempt?
Ever hear of WD-9? How about WD-23 or WD-37? Why bother making another attempt; which we now know as WD-40?
One last one – Wheaties, “The Breakfast of Champions”, was created by accident! A technician spilled a batch of bran gruel on the stovetop that quickly crackled into flakes. However, it took 36 attempts to make the flake stable enough to box and ship. Why bother with this “beneficial accident” at all?

How many times have you wanted to quit a difficult task but decide to give it “one final try” and suddenly succeed at what you had been failing? Why, may I ask, did you even bother to try again?
Words such as “stubborn”, “focused”, “single-minded”, “deranged”, “strong-willed” and “bullheaded” are often used to describe people who achieve great success. The word I prefer to use is “determined”.
determined – “having made a firm decision and being resolved not to change it”
You continue banging your head against the wall because you are determined to resolve the issue.
And, why are you so determined?
Because you have committed your time, energy and resources to the resolution.
committed – “feeling dedication and loyalty to a cause, activity, or job”
Your success is directly related to how determined and committed you are to the task at hand.
So, I guess if you’re not determined and committed…
…why bother?
