First of all, I'd like you to do something: Just take one little moment, sit back, take a deep breath in, let it out and close your eyes. Now ask yourself the question how is your feeling of time and space at the moment? Is time running away from you? Is it stuck, not willing to get over? Is the place you are now wide and spacious or small and stuffed? How are you feeling in this situation?
Personally, I just made once more the discovery how different the same time is experienced by two people. How different the feeling of space in the same room is at different times. Although time is a unite measure applied by everybody without exception, it nevertheless seems to be flowing at a different speed for all of us. An hour can feel like a week if you are waiting for your friends to arrive at the meeting point in order to begin an awesome trip together. A week can feel like an hour if you spend it with good people at a good place and you really don't wan't to go home. A 3 1/2 room flat can appear terribly small if you are longing to go to the above mentioned trip, but then again it can feel tremendously big and spacious after one week as four and then returning while your mum is on a business trip (which means you have the whole flat for yourself - yay!!..right?). And then again in this empty flat one day passes by, seeming short as the blink of an eye and never ending at the same time.
It's not hard to believe that the ancient Greeks once thought that there was a god named Chronos, who ruled over time and life time. We may not always be able to influence how fast time passes by, but it is we who decide wether we consider our time as "ripped away from us", "cruelly slow ", or "lived/used to the fullest".
If time appears to be to fast, try to step back and appreciate the small details as for example the marvelous smile of your best friend sitting by your side at a turquoise colored mountain lake after you just took a bath (despite cloudy weather and only 15 degrees water temperature) , the sound of everybody's laughter after you brought the full (and pretty heavy) equipment to hold a perfect barbecue with you and realize after a long hike that you are not allowed to make a fire (ooh well, it was a good work out) and the smell of bonfire smoke inside of your own house (we went home in order to hold our BBQ, but it suddenly started to rain, so we used the old fireplace inside the 400 years old house to barbecue our meat at last!). If you do this the time may not appear slower, but fuller.
If time is racing because you're stressed, try to look at everything with a bigger distance to gain back the overview without loosing the eye for important details. By gaining distance you are able to find once more what really has priority and what only seems to be important but could wait a little longer.
And finally, if time passes too slowly, try to entertain yourself to the fullest while waiting for it to get over. If school is boring, try to use that time to get better at something (gaining useless knowledge, improving your conversation and social skills together with your fellow sufferer to your left/right , getting better in art by drawing sketches in and on your notebook, improving time management and multi tasking skills by doing home work during lessons - there are tons of reasonable activities). If that is not possible, you just need to remind yourself that the whole world is just one big stage and that you are always director and actor rolled into one. Once you do that you'll find the biggest entertainment in the most boring meeting at your work place (Wow, what's with this expression?! Did my boss always have a nervous twitch when talking enraged? By listening closely, John, that smoothy from team one lisp a bit, doesn't he? Wow, actually I never noticed how beautiful the view from this meeting room is..). Of course no one needs to know of your "discoveries", in most of the cases the conversations inside of my head with myself are amusing enough. A good alternative would be to engage yourself into daydreaming (if affordable), as you'll get better and better and experience more improved daydreams and adventures by practicing it.
Of course it would still be the best to just always live in the moment as Zen, Buddha and who knows who else are preaching, but until I have have the answer on how to do that, this is how I try to be ruler of my time and gaining the most out of it. If you know anything better, by any means, please share it in the comments below!;)
