The Secret Master Plan your company badly needs

Tesla (finally) released the $35K version of Model 3 yesterday. This, in some ways, finalizes the “secret master plan” from 2006:
“So, in short, the master plan is:
Build sports car
Use that money to build an affordable car
Use that money to build an even more affordable car
While doing above, also provide zero emission electric power generation optionsDon’t tell anyone.”
I wonder how many companies work like this, where you have a huge and ambitious goal, split that up into subgoals and let each subgoal finance the next one.
Most companies reach a plateau where they let the revenue generated by their existing business simply optimize what already works. There is no huge and ambitious goal in the distance, there is only the day to day operations and how to be 3% more effective.
In a world of constant change, this inevitably leads to stagnation and death.
Sure, Tesla is a risky business and can most certainly stumble on their way and collapse, but at least they did it trying to seek impact and achieve something great. And the reward, if they succeed will be huge. HUGE!
So, what’s your “secret master plan”? (I promise not to tell anyone.)
