Many by their efforts are able to create a world or empires for them selves. Have you ever thought to ask them how come they made it so big in life?.
Some may say dedicated and persistence but they sometimes leave out the hard truth"*** failure "***.
Yea failure is the master key to success. If you don't fail , you won't succeed .its as simple as that.
Many people amass a lot of degree and masters and phds yet still their life's can't count the real success because all the have are degree and nothing else to show for it.
People like that , have practically not risked anything in life because they always want to play safe.
So they never experience failure.
The reason for stressing so much on failure is that people thing failure is a bad thing but rather it shows whether you will succeed or not.
Daring people like great inventors and scientists all had their fair share of failure. Einstein ,newton , Jordan, Henry ford, Kirchhoff even presidents Lincoln and visionary people like Martin Luther king all experienced it ,before becoming who they were.
So people ,if you fail at something doesn't mean it wasn't meant for you. Try again and again and you will be surprised at the results, don't be scared of failure but rather embrace it and it will show you the way , because how you rise after you fail tells you of your future and what success has planned for you.
