When you’re not achieving your goals to your level of expectation, how do your thoughts and feelings change? Even highly skilled goal setters experience delays and changes, but how we perceive these hurdles is what can make the difference. Maintaining a positive outlook keeps us from slipping into the downfalls pessimism can cause. This negative thinking can increase cortisol levels, stymie creativity, and generally distance you from success. So, even if staying positive just keeps you neutral, you won’t lose ground on the progress you’ve already made.
