If you have the drive to be an entrepreneur, there is no end point. Quitting is not a choice, even when facing tough obstacles along the way, there is still the internal spark to overcome and construct new path. Entrepreneurs do not know the meaning of the words "can't", "wont", or "die".
There are many things that can happen to you and your company. Some are good, others are not as pleasant. Change is the only constant with the passing of time and adapting is an important trait in the world of entrepreneurial success. You, and those around you, should not be surprised by your continued push forward.
Your company may fail. It could run out of money or you may decide to walk away to free yourself up to be ready for more appropriate opportunities. You might have an exit event where you sell your company (that can be a really good thing!). Possibly you may keep ownership of the company, but turn the reigns over to another person to take the business to the next level of growth.
No matter what the reason, those separated from one company will most likely move quickly onto a new project. The journey is never over for those who are called to create. Like an artist, an entrepreneur will simply find a new canvas and begin something new.
The new adventure could be another start-up, working as an intrapreneur for another established company, joining the world of non-profits, or any of several other option. Regardless of what you do next, there is rarely retirement for those who carry the entrepreneurial spirit.
There is no end of entrepreneurship.
Have A Great Day.
