One executive is driven by stimulants: salary, bonus, company car, title, promotions, etc. Another executive is driven by a purpose to make a difference in helping an organization to be as successful as it can be in the short term and the long term.
Neither one of these people exist.
No one is completely stimulant-fueled or purpose-fueled. However, which end of the spectrum you are closest to will impact your long-term performance. Stimulants are provided by someone outside of you. They have to be continually increased in order to fuel better performances, or even to maintain the status quo. Purpose comes from within you, and a great sense of purpose can fuel you over an entire career and continually generate greater performances.
I encourage you to focus on the purpose of your work, which only you can define.
