This book describes Perseverance (Persistence), Diagnosis and Treatment and Related Diseases

Perseverance is the name of the Mars rover that has just reached the surface of Mars.
It is called Perseverance because scientists at NASA believe that perseverance helped them not to give up.

"Our greatest weakness lies in giving up.
The most certain way to succeed is always to try just one more time."
- Thomas A. Edison

"If you can keep your head when all about you
Are losing theirs and blaming it on you,
If you can trust yourself when all men doubt you,
But make allowance for their doubting too;

If you can wait and not be tired by waiting,
Or being lied about, don't deal in lies,
Or being hated, don't give way to hating,
And yet don't look too good, nor talk too wise

If you can dream - and not make dreams your master;
If you can think - and not make thoughts your aim;
If you can meet with Triumph and Disaster
And treat those two impostors just the same;

If you can bear to hear the truth you've spoken
Twisted by knaves to make a trap for fools,
Or watch the things you gave your life to, broken,
And stoop and build them up with worn-out tools

If you can make one heap of all your winnings
And risk it on one turn of pitch-and-toss,
And lose, and start again at your beginnings
And never breathe a word about your loss;

If you can force your heart and nerve and sinew
To serve your turn long after they are gone,
And so hold on when there is nothing in you
Except the will which says to them: 'Hold on!'

If you can talk with crowds and keep your virtue,
Or walk with Kings - nor lose the common touch,
If neither foes nor loving friends can hurt you,
If all men count with you, but none too much;

If you can fill the unforgiving minute
With sixty seconds' worth of distance run,
Yours is the Earth and everything that's in it,
And - which is more - you'll be a Man, my son!"
―Rudyard Kipling

I have not failed. I've just found 10,000 ways that won't work.
Here, we learn to congratulate ourselves on finding ways that don't work.
Why? Because with each failed attempt, we are closer to discovering what will work.
The more failures, the better - ultimately leading to a climax of success.

Don't beat yourself up over not getting a job, promotion or business opportunity.
Instead, know that it is a necessary step on the road to finding the right destination.

Edison, a man before his time, knew that busyness for the sake of busyness is pointless.
It's about results.
And you'll get those from proper planning.
You won't get them from mindless busyness.
Persistence is not about being busy.
It's about following a well-thought-out step-by-step plan.

The word Perseverance means to continue to do steadfastly or try to achieve something despite difficulty, failure or discouragement.

Its use depicts a personality trait of spirit, and firmness of mind dating back to the early 1800s

Perseverance is a personality trait that pushes a person to overcome difficulties.

Perseverance (Persistence) is a term that is said to call for both excitement and declaration in service of a long-term goal.

Perseverance is a lengthy run, not a sprint, as they say.

In other words, persistent people put in sustained effort over time to attain a high level of success in their chosen area.

Everybody likes to hear about the overnight sensation that made it big...
