Challenges and difficulty nurtures hard work.
...Now don't get me wrong here - some may say that it may do the inverse where the challenged become overwhelmed and give-up or move to something within their comfort zone....I am not discussing that paradigm.
Working hard-ER is a mentality, a culture, a lifestyle
According to your passion you work be it for: love, money, appreciation, grades etc. you work hard....
What about the "er"?
To be extraordinary then hard-er is the key. Self motivation, goal scheduling and a strict routine become an innate religion.
To be original means to -ER everything.
..for your passion - go hard-er, fast-er, become hungry-er,
at the end I am sure the journey with all the processes I will become happi-ER...
Some how many don't like to work hard...
Is it cultural?
