You’re an entrepreneur. You chose this lifestyle and its ups and downs. Insanity aside, how do you survive it? Sure, there’s the age-old “positive thinking leads to positive outcomes” mentality, but if it were that easy … would we even need entrepreneurs?

Instead, start by cutting the negative stuff out of your life and surrounding yourself with the positive. Not only do you lack room for nay-sayers and negativity in your life, it’s making you less smart.

“There is little difference in people, but that little difference makes a big difference. The little difference is attitude. The big difference is whether it is positive or negative.” – Mark & Angel Hack Life.

Take inventory on what’s dragging you down and what’s killing your intelligence. Now make the decision to change it.
