As I've helped people through the generalist to specialist transition, I've realized that success really comes from the how good the implementation of the specialization decision is, not how high quality the decision itself is. You can make the most amazing, high quality specialization decision possible, but if the implementation of that decision is low quality then you'll get dissapointing results.
The paragraph above needs a serious footnote, so here we go. There are places in the maturity of a self-made expert's business where the quality of a specialization decision absoluely does matter a lot. This is generally true of more mature businesses.
But at the very outset -- at the generalist to specialist transition boundary -- what's much more important is getting in motion. You can't steer a parked car, can ya?
Those of us who have learned to ride a bicycle have learned this lesson in a very physical way. During those first 1 or 2 seconds of getting the bicycle moving, what matters the most is... getting the bicycle moving. If you obsess about steering the bicycle in a really accurate way during this time period, you'll get distracted from the primary task, which is again, to get the bicycle moving. You'll wobble. You'll risk falling over because the wheels aren't contributing gyroscopic stability and your small steering corrections don't help you stay upright.
Once the bicycle is moving, how you steer it matters a lot more.
That's why the upcoming workshop on specialization focuses on momentum rather than accuracy. If you've never specialized before and have a business that is relatively newer, this is the correct approach.
