how to teach kids to wait

i have trouble teaching michelle to wait.  she thinks waiting is a matter of seconds.  kids do not understand the full concept of time yet and today's technology makes teaching them to wait a little harder.

when i was a kid, cartoons will be on tv only on weekends so i know to wait for the weekend so i can watch cartoons.


traveling from point a to point b used to take longer but now, traveling is much faster and our gadgets seem to make time fly faster.  


but michelle's generation have everything at the tip of their fingers.  if they need to talk to mommy and daddy, they know someone has a cell phone somewhere and they can make a phone call anytime, anywhere.   


while watching tv one time, she needed to use the bathroom and she wanted me to pause the tv (our bedroom tv does not have dvr/tivo).  when i said that she can't do that, she gave me a puzzled look like i was crazy or something.  i had to explain to her that not all tvs work that way.


in the car on a drive somewhere...similar thing.  she heard a song she liked and she said, "mommy, rewind please.  i want to hear the song again."  i had to explain to her that it was the regular radio and i can't rewind the song.  we used to have satellite radio in the car so she thought all radios can be rewinded.  when our free trial ended, i didn't bother renewing.  i still don't understand the concept of paying for radio because i am not sitting in my car for long periods of time. 


power outages are uncommon here in the states.  she's 5 and she's only experienced 1 power outage.  that was an exciting time for her because it was new to her...but i recall back in the philippines in the early 90s when each and everyday will be rolling blackouts of 4 hours or longer.  the heat and the mosquito bites were unbearable!


do you have any tips on how i can teach her to wait?
