As for having evermore business flexibility, having evermore personal flexibility isn’t necessarily good. On the later, seeking ever more friends to build your personal network means spending less time supporting the friends you already have. Trying endless activities gives you a life of rich, but shallow variety (think of sampling many kinds of sweets in a sweet shop, rather than having one satisfying meal instead). Encouraging your children to do what they like, eventually leads to some bad outcomes. Paying for ever more features and options becomes expensive and counter-productive. Committing to help in areas where the workload fluctuates wildly (or going beyond healthy lifestyle choices) won’t have a happy ending for your health.
So is there an optimal level of personal flexibility – enough to give someone a rich and rewarding life. But not enough to exceed the limits of their health or good reputation? Probably. All we can do is try and figure out if having more personal flexibility is an improvement over the current state.
The point after optimal personal flexibility might be a gradual decrease in benefit. Or a dramatic decrease. This is a fascinating area worthy of future study, to see if certain kinds of personal flexibility generally drop away fast/gradually on any kind of predictable basis.
However, because the subjects of business and personal flexibility are still emerging, the research hasn’t been done. The nearest we have are economists look at marginal utility and finance professors who look at the value of options held.
Because personal flexibility is a wide subject and since flexibility can take many forms, all we can do is monitor for negative flexibility at a personal level, until theory catches up with reality.
