Hard work is the royal road to success. 

The greatest success happens in discomfort.

Those who are successful are the ones who were always working very hard.

Those who want to be successful must suffer and accept pain.

Those who are successful were going through pains.

Introspect yourself through hard work.

Fly high like an eagle and the sky will no longer be a limit when you are successful 

Indeed perseverance is the mother of success.
