Yes, that is what I mean, also suggest once you get so you can switch between two or three of the chords you choose, without looking at your fingers while singing. Start using real words to your real songs.
There is a difference between, sing out loud, like in a mic and singing quietly to yourself. So start like you are singing in a mic to a crowd. That brings up another good point, your voice will sound completely different to you through a PA, try to get use to that soon. Even a cheap mic through your first amp if you still have it. Make sure the mic is not in front of the amp and have the treble turned down some when you turn it on. It helps avoid feedback.
Stand straight so you can breathe well, project from your stomach not your throat and nose.
Try to record yourself so you can listen back.
