Have you ever asked yourself what you want to do with the guitar when you have enough skills?
First-time beginners can strum with 'Sweet Home Alabama.' It's not much, but it's better than nothing. The point is, even with only basic skills, you can do constructive things with music. You don't need advanced skills before you can put your skills to work on something - anything.
Nothing improves your skills better than interacting - playing - with real music. If you're doing it right, it should be fun. But it might be a little frustrating at first. Beginners are always getting hung-up on a minor problem that will disappear forever if they just work through it for five minutes, maybe even just three minutes. That's when a good coach can be really valuable.
But the real question is your motive, your reason for playing. Many people don't have a particular reason for learning to play, no musical dreams. Just something to do. That's fine, but it still gets back to 'What do you want to do?'
You've got two basic choices: you can play guitar alone, or you can play guitar with other people. You can also play with recordings. Playing with recordings is the best preparation for playing with bands because it simulates the experience of playing with other people.
If you're not playing with recordings, why not? If you play at all, then you have the skills to play simple songs with recordings right now. Playing with recordings is fun, challenging and highly educational. It's good for your technique, strength and endurance. It's preparation for playing with bands. It's a benchmark for your skills. What are you waiting for?
