The 3 Ts, Timing, Taste and Tone

Let's start with #1, Timing.

The key to sounding good is the ability to keep a rock solid, steady beat. Nothing is more frustrating than to play with or listen to a musician without good rhythm. How do you develop this sense of timing? In a word,  METRONOME! It's amazing how many people balk at using a simple tool and continue to struggle with timing. You can purchase a metronome for as little as $20 or even find one for free on the internet.

How does it work?

You set a tempo, (speed), and practice slowly so you develop a sense of timing. Think of this as the pulse of your music. Like your heartbeat it should be steady and rhythmic. A beginning guitar student can start with a simple timing pattern using open strings. The important thing at first is to play something easy so that note reading isn't the problem. Play whole notes, half notes and quarter notes, then build speed. Your guitar teacher can give you more details.
