Instant noodles, instant coffee everything we need instantly in today's fast moving world. And finally what's the end result? Instant karmic reaction which is only multiplying the pain that we already have. People who are thoughtful can understand the defect of material sense gratification. We want to enjoy our senses right now & get pleasure. But the material nature won't allow us to do so beyond a limit. The more we try to enjoy the senses, the more we suffer. That's how this world is designed. 

A person who is not disturbed by the incessant flow of desires-that enter like rivers into the ocean which is ever being filled but is always still-can alone achieve peace, and not the man who strives to satisfy such desires.

Bhagavad Gita#2.7
