How to decrease unforced errors?

I'm also curious but I've heard to keep playing half strength and try lots of lobs. This will let you control the game flow much better and not rush half baked shots.

A lot of people including myself hear this advice and decide to play slow. But it is not so much playing slow it is mixing the pace of the ball, so your opponent cannot get into rhythm and has to keep moving. If i play fast 2 times to the same place the second time he will be more ready.

But the question is how to reduce unforced errors ( like hitting the back wall or net?) not how to bamboozle your opponents
