Determine whether you are a global or specific person. Most people are either too general or too specific in the way they treat information, and overly detail-oriented people risk losing sight of the bigger picture. General people are more comfortable in managerial positions, while detail-oriented people prefer everything to conform to a logical sequence.

In order to be happy and successful it is important to surround yourself with other people who are happy and successful. Positive energy spreads quickly–just as negative energy does. You life is valuable and your time is as well. The last thing you need in your career is to deal with another person’s constant negativity.
