Also, use the whole fretboard. If you only use the first three frets, the soundboard won't be responding to higher frequencies. So you're only "opening up" lower frequencies. So later when you start exploring the fretboard, it'll sound different which may dissuade you from using those higher notes.
This is apparently a problem people have who buy Martin guitars from the 20s and 30s. They were only used for open chord strummings using the first five frets... people buy them today expecting an insanely good experience, and it sounds "meh" in the higher register.
Since different parts of the soundboard react to different frequencies... yeah.
But I'm assuming it's a solid wood, and not a laminate, that you have.
