Entrepreneurs are a fickle bunch. Many, like myself, can be control freaks at times and drive people crazy. In the same light, the company, product, etc are a reflection of your vision and goals. In Andre Agassi’s autobiography one of the recurring themes is his coach reminding him control what you can control.
Entrepreneurs need to control what can be controlled and move on otherwise.
Here are some things that can’t be controlled by entrepreneurs:
- Economic conditions
- Competitive forces
- Change
- 24 hours in a day
As you can see, most everything that entrepreneurs want to be controlled can be controlled. My recommendation is to control what you can control and stop worrying about the rest.

“The” leading indicator is firm/company capability. Firm capability increases leads to firm revenue increases. Firm capability is the one thing owners can control. Can you make desirable products, generate leads, serve customers, attract talent, etc.? Focusing on these controllable items is what counts.
