Single unit value

Here’s a question to ponder about making an impact:

If we can only make a small amount of impact with our finite amount of time, is it more valuable to create an incremental gain, or create something new?

i.e., is 100 to 101 more valuable than going from 0 to 1?

Sure, real life is much more complicated than this, but the core question remains:

Is it worth focusing effort on something which is already OK, when something else hasn’t even been looked at yet?

Personally, I’d rather shift the margin than polish the centre.
