Time does not fly,
your perception of it, does.
you can keep track of it and you'll see how efficient it can be. how precise and how on point it will be.
keep track of your time, and take your fate in your hands. lose it and lose your present and the future.
you don't need to do things the way it makes you uncomfortable but if it's necessary to do, find a way to make it bearable, or amusing or interesting and awaken your curiosity again.
when I have an appointment, and there is no time to waste, I understand the value of time and if we are caring about it we should know even those times that we are wasting, sometimes seems to be just an excuse to be on wrong again and not get blamed for it. I mean, what's the reason behind it? I'm not saying what is better to do and what's not, or what's worth doing and what's not. I'm saying if we're just doing everything for fun, we'll go nowhere, but if for example we play games and we persist on getting really good at it, it gives us a reason to live for and that's what we need all the times during our lifetime. it's not a matter of being 15 and doing this, you can be at any age and still believe in yourself and try to get better at your games, that alone can give you a reason to take care of your time and yourself and can also bring a lot of rewards and take you somewhere that you wouldn't even imagine it.
