It's fine, different people prefer different time settings.
Long Games=Good.....Short Games=Bad
I thing blitz games aren't good, bacause you can't seriously think about moves. In logn games you can have a deep plans, and you beter can calculate variations.
If you want to play blitz you must known very well openings, and can speed calculate variations.

Learn to speed calculate. It makes you smarter.

All the "serious" games I play are 15.10, and I play 2.0 games to escape from reality. The quick games can be quite exhilarating, but I'm pretty sure they haven't had much of an effect on my long games, good or bad.
Short games are good for practicing your ability to spot simple tactics (and recognize opponents' threats) quickly, and for getting better at playing under time pressure (e.g., you're playing a long game but your clock is running out). Long games are generally better for practicing most other aspects of chess.
With a longer game, you have more time to think - so the quality of game is usually higher. You're not alone in that.
I remember the movie "Searching For Fischer". Josh was a great chess player and his father secured a coach for him. Josh was good at his game. Josh also enjoyed playing quick games. His coach advised him not to play those type of games because it was bad for his tournament games, because it created bad habits. If I remember correctly later in the show Josh went back to the quick games because it was important to just have fun with chess. Playing slowly improves your game because you have time for thought, and planning. Both are good for different reasons just understand the difference and enjoy the game.
I've played chess for some time. Not seriously or anything. And I've just now started playing online this last month. and I've notice on my On-line and Live matches that are Long (30mins+ is what i usually play) I do fairly well at. But if 30 minutes or less is all I have for a full game I do poorly. I don't know what it is or why it is. Most of my Long games are over within 15-20 minutes time wasted, but i just feel less pressure on making moves. Any advice? Or is fast thinking not my thing?
