Being defeatist or focusing on what others have that you don't isn't just distracting, it can stop you from moving forward. According to 26-year-old CEO Brian Wong, taking steps to avoid this type of thinking is one of the best investments a person can make in his or her career.
"It's a waste of time to compare yourself to the upper echelon of the whole world," he says. "You'll always lose and when you do, you'll feel like a loser."
The CEO recommends instead that professionals focus on improving themselves.
"If you can be a better you every day, you can win the race."
Scientific research shows that grateful people are more likely to be happy and successful. Keeping a journal of things you're grateful for (even if it's in a small notebook that you store inside your desk) could help.
A widely-cited study by UCLA and the University of Miami found that people who wrote down what they were grateful for on a weekly basis were more cheerful and optimistic about the upcoming week than those who didn't. They also had fewer doctor visits and missed fewer days of work.
