Yes. We can improve ourselves, our professional work, our families, our communities, our society, and everything in an incremental way.
While taking radical and aggressive action can work well in the right circumstances, it is more effective overall to work in a consistent, disciplined, and continuous way on incremental improvements. Improve your average, do a little better every day, and over time you will have big changes.
We do not have to address every problem at once nor do we have to make things perfect on the first pass. We need the pressure to improve but we should not lose the good in search of the perfect.
