No one limits your growth but you.
If you want to earn more, learn more.
That means you'll work harder for a while; that means you'll work longer for a while.
But you'll be paid for your extra effort with enhanced earnings down the road.
-- Tom Hopkins
No input = No output
Some input = Some output
More input = More output
The more you put into your learning, the more knowledge you earn in your learning journey!
No one can limits your growth but you may set a limit and block your own path of learning.
