What does the future hold?
We don't know. It could hold absolutely anything. The future is a blank canvas.
If you think that changing jobs or changing companies is a big deal, think again.
The future doesn't have to be a simple evolution of the present. The future, beginning in this very next moment, could be a dramatic departure from everything before.
The only limits are your thoughts (and maybe some physical requirements if your goal is to play center in the NBA).
What is your dream? What would it take to realize it? What if you started doing those things today?
If you want to stay in your cage, that is an absolutely valid choice. But understand first that you built the cage, and you have the key to the door.
