Can Overcoming Procrastination Be Boiled Down to a Formula?

Can your chances of overcoming procrastination be determined by a simple mathematical formula? According to an article in Times Online Formula for overcoming procrastination ... what are the chances? a business professor in Canada claims you can.

Professor Piers Steel collected "hundreds of studies on the art of delay" for his book, The Procrastination Equation: Today's Trouble with Tomorrow. The professor claims that there are two prevelent opinions about people who practice this "art of delay." People are either of the following:
Extremely careful
Do-nothings

Steel proclaims that procrastinators "have a vice all of their own. His "evidence suggests that chronic procrastinators, who make up about 20% of the population, are more impulsive and erratic than other people and less conscientious about attention to detail and obligations to others."

This is all very interesting. However, I do not think that procrastinators should be merely catagorized as "extremely careful" or "do-nothings" or "erratic" or "less conscientious" nor do I think that a person's chance of sucess can be or should be boiled down to a mathematical formula. I like to think that human beings are capable of endless posibilities. I do admit that there are many variables that have an effect on whether we overcome our procrastination or not.

Because the book is not yet at Amazon, I have not been able to read the elements of the formula. If some of the variables in the equation are: how clearly we can see what we want accomplished; how strong our desire is for that which needs to be accomplished; how determined we are, then perhaps there may be an element of this equation that I can believe. If the professor takes into account that our brains have a hard time processing when our desires conflict with each other, perhaps I may ponder his formula. But, I think he would have to do some really great explaining to convince me that to overcome procrastination, all one needs to do is work on the variables of a simple mathematical equation.

I would love to hear your thoughts on this catagorization of procratinators.
