Sense of time: Evaluation and correlation with psychological traits and states Some of us are often in hurry and always late. Some make mistakes while evaluating time-needs for tasks. How is our sense of time connected with our personality? Is it more correlated with the process we are involved in? How we can develop this sense so to make more of our time?
People who are entitled tend to have a slower perception of time. In any given situation, a person can feel some level of entitlement. If a person is waiting in line for 10 minutes to check out groceries, he would experience that 10 minutes as passing by very slowly. On the other hand, if that same person was waiting 10 minutes to meet the President, he would experience the 10 minutes as passing by quickly. 

So time perception can be manipulated in any given situation. It depends on the level of entitlement you are feeling in that environment. Perhaps entitlement could artificially be manipulated to create different perceptions of time (e.g. by thinking quickly and variably).
