user7152: What do you say about it?
I find that if you're in a sequence that you're realizing is a trap, and the pressure on you is building. Or you've blundered, or worse, you deservedly are about to get crushed—its a traumatic experience where the ideational nature or principles of the position are more readily gleaned.

user7827: Like sprinting vs. a marathon, both styles of game are valid but build different skills.  Blitz chess is all about "board vision": the ability to quickly recognize tactical patterns, identify threats, or just create an innate sense of where the pieces should go.  Longer time controls exercise computational skills: the ability to "go deep" on exchanges or set up a tactic.  
Playing only one style may help you win sooner, but I would argue that playing both will help you win more often.

user7245: Yes, more longer the game you can play, it can test your concentration, visualization and memory power.
When I initially started playing Chess, I was always excited to play blitz Chess. I kept playing and finally I couldn't improve my Chess as I didn't improve what was needed.
Recently I played with a time control of 1 hour in my debut FIDE tournament, I took the most time for my moves against my opponent. All 9 players I met in the field were having Class C rating but then they had the basics right. I could win against 6 and drew with one while losing the remaining two because of minor blunders. Luckily, I could open my FIDE rating in my very first tournament, though the rating is not much to be proud of. It set a platform for me to concentrate more on longer games and less on blitz.
