I definitely agree with this. I bounced from deadline to deadline for seven years in late high school and university. Addiction to deadline-driven activity is now causing me tons of grief when it comes to anything not required by an immediate deadline at work. Career development, outside-of-work life planning, calling companies about that wrong bill...

This is definitely the case and was actually something I was going to plan on addressing in my initial comment about procrastination before deciding that I could put it off. :)

While I did not make it clear, the formula presented within the essay remains applicable whether or not someone is motivated by eustress, except that the formula changes slightly:

                   expectancy x value
  motivation  =  -----------------------  +  eustress
                  impulsiveness x delay

Using this formula, an incredibly low-value task (in my case, school assignments) can still have an acceptable (or greater than) outcome when complimented by a high level of eustress. (In my case, this is often in the form of an impending deadline.)

Other than school, however, I have been working with a friend, attempting to launch my first startup. This is an incredibly high-value task for me, which leads to greater motivation despite a lack of solid deadlines. In this case, I procrastinate very little.

That's not, of course, to say that every task related to launching is high-value. In those instances, you are correct, aggressive goal-setting is absolutely necessary. I'd add, though, that it's not simply an attempt to "keep this sort of thing up," but rather a simple acknowledgement of how I function.
