How to pick time tricks ?

I have always been short of time. One of the greatest challenge seems to be managing time. It won't be there when i can give an eyeteeth for it but it is always there when i don't want it. Finding yourself at some occasion where unfortunately you ar not having anyone to talk with. We have to find one way or the other to kill this time. Or say, i am at Dadar station and want to catch a train to Borivili but i've just missed one . So, i have to wait for another 10 mins. Now what to do ? Staring blankly at people or what else ? Sometimes i buy a magazine to "utilise" such time-gap. But i couldn't even finish the editor's message that the local arrives. Now short on time. hmmmm. Want to prepare an urgent report but some friend (or fiend, that time) calls up. One has to just kept saying hm, hmm, hmmm, hmmmmm till the time the friend says " i think you're busy". Recall the exam mornings, i want to see that book ( God knows, how all the bird view techniques we learn on that very morning), that notes and yeah i have scribbled something on one register also.....
By now, i should have prepared some reports, taken snacks at the canteen (missed my lunch) but i am busy writing this post. I know i'll be delayed but what can i do in this ? Time is like that only ?
