"Time is an invention of man", said my spiritual teacher, a Tibetan lama. And another one, asked why time seems so long to children and so short for grown-ups, answered: "Children don't have their heads full of thought-concepts, but just watch what is happening -- yes, I think this is why." (He is father to 3). Could it be that the solution to the problem of "having no time" is just to watch what is happening -- without concepts and thoughts? Ha, how to be without thoughts? No, you don't necessarily have to be without thoughts -- just don't let them conquer your mind. This happens when we get entangled in sequences of thoughts, trying to find reasons and drawing conclusions.
I once noticed that if I have the choice between to urgent tasks, I choose a third one which is idle and just fun. :-) This makes it easier to find out which of the tasks is really urgent -- if it is at all. But if it is, I don't hesitate.
Screens are time robbers! TV is worst. It is worse than the internet, because you are passive and get hypnotized by the motion on the screen. The faster it becomes, the stronger the urge of the brain to relax and let the pictures just float by. This is why tv is the strongest time robber. Proof: if it is broken, you feel bored, then you start observing what is around you -- and you seem to have a lot more time.
