Ever think about how people are always saying how quickly time is passing by. It is especially noticed when someone goes away (travel, work.....) for a month, year, couple years- whatever be the case. I have observed that for the person who goes away to them they feel like they have been gone longer than that time period. Verses the people they left and come back to it normally feels like a much shorter period of time that that person has been away. I'm no psychologist but am guessing it has to do with routine. If you are in a routine with few things changing around you time will pass by quickly. You are basically doing things without thinking. However if everything is always changing (such as when traveling) you have to constantly be alert and aware of your surroundings in order to stay safe and get to where it is you want to go. What I am getting at is if you do not want time to pass you by, break that routine and do something new (mix it up). For other people who want time to pass more quickly (which is a shame since we have only so much of it) get into a set routine and strictly follow it. Time is constantly passing by all of us are we making the most of that time which we have been given.
