8. Keeping a positive outlook.
Consider the most successful person you know. Is that person positive or negative? Most likely this individual is positive, enthusiastic, energetic and happy. This person chooses to see the good in others and in himself or herself. To this person, problems are just opportunities waiting to be uncovered.
Every day people are bombarded by news of bad deeds and doings. Successful people minimize their exposure to this type of thing and instead opt to fill their minds with positive ideas from books and magazines.
