Nothing in the world can take the place of Persistence.

Talent will not; nothing is more common than unsuccessful men with talent.

Genius will not; unrewarded genius is almost a proverb.

Education will not; the world is full of educated derelicts.

Persistence and determination alone are omnipotent.
The slogan ‘Press On’ has solved and always will solve the problems of the human race.

Calvin Coolidge (1872 – 1933) 
It’s been said many a time – those who succeed do so because they weren’t prepared to give up at the first sign of difficulty. They kept going, they showed Persistence…
Seth Godin’s book “The Dip” however seeks to question that established wisdom –
“The old saying is wrong-winners do quit, and quitters do win.
Every new project (or job, or hobby, or company) starts out exciting and fun. Then it gets harder and less fun, until it hits a low point-really hard, and not much fun at all.
And then you find yourself asking if the goal is even worth the hassle. Maybe you’re in a Dip-a temporary setback that will get better if you keep pushing. But maybe it’s really a Cul-de-Sac, which will never get better, no matter how hard you try.
What really sets superstars apart from everyone else is the ability to escape dead ends quickly, while staying focused and motivated when it really counts.
Winners quit fast, quit often, and quit without guilt-until they commit to beating the right Dip for the right reasons. In fact, winners seek out the Dip. They realize that the bigger the barrier, the bigger the reward for getting past it. If you can become number one in your niche, you’ll get more than your fair share of profits, glory, and long-term security.
Losers, on the other hand, fall into two basic traps. Either they fail to stick out the Dip-they get to the moment of truth and then give up-or they never even find the right Dip to conquer.” from
Which school of thought do you think best sums up how things really are? Have you ever felt like giving up on something, only to have second thoughts and give it another try? What really makes the difference to a project that remains just a great idea, and one that flies?
