I read this article and really liked it.  

Without wanting to sound horribly cynical (because honestly, I'm really a glass half full kind of girl) I'm pleased to see some hard truths in amongst all of the mindless optimism and quick fix motivational quotes that my social news feed seems to be filled with these days.

Yes, working harder than everyone else will get you somewhere.

It's true that having a "great idea" will get you on the right track.

"Luck" or Timing will certainly help too.

But above all, being brutally honest with yourself is the secret for paving your way to success.  

True to PIE style, "NO BULL" - whether you're an entrepreneur or carving out your career with an employer, the same principal applies.

The article spells it out perfectly, a good - if a little bubble-bursting - read.
