Hi BP9,

I second what john of MT advised, regarding the strap and the mirror.

With the strap, you want to make sure and adjust the length of it so that it is giving your upper body some help in stabilizing and supporting the weight and position of the guitar.

Sometimes finding the "sweet spot" in terms of strap-length may come down to an adjustment of an inch or two in length, this way or that. 

The more that the strap is doing the job of supporting your guitar, the more you can afford to bring more relaxation to your shoulders and arms. 

In terms of your left-hand fingers getting more confident of their placement on the neck to make various notes or chords, see if you can pick out two chords that are relatively easy for you (let's say, D7 and A7, for starters). Practice going back and forth between those 2 chords until they feel pretty solid, THEN, CLOSE YOUR EYES and keep it up!

Your hands are in the process of getting the "feel" of the layout of strings and frets on the guitar, so they won't need so much supervision from your eyes further on down the line.

There will come a day when you say, "I can't believe I used to have such trouble with this - it feels easy to me now!"

Best of luck, and have fun! - Lisa
