“Success is a lousy teacher. It seduces smart people into thinking they can’t lose.” - Bill Gates
The best way to get results is to act. The best way to learn is to fail. Success is not the end of the line, it is just one step along the never-ending journey.
You still have to be careful with your decisions. Nothing in life is guaranteed. You could easily throw all your success down the drain if you get too arrogant or overconfident in yourself.
Be humble when you are successful and learn as much as you can from your failures.
