Positivity, by contrast, is directly linked to improved performance.

What is grit, really? It’s a word that’s been used to describe everything under the sun, but it means something specific: when things get hard, you push harder; when you fail, you get back up stronger; when you don’t see results, you don’t get discouraged, but you just continue to pound away day, after day, after day, with relentlessness, consistency, heart, and passion – that’s grit.

But talent without grit is just potential. Talent plus grit is unstoppable.

Like everything else, excellence is a habit.

People successful in life, in business, and in relationships are living into a process that leads to excellence; these are the people who get up early to work out, who say no to crappy food, who carve out time for learning and mindfulness.
