assistant: Learning to play guitar can be a very different experience for different people, so a generally appliable training plan does not exist. You should train playing the guitar in your own pace, for which a presence of a guitar instructor would be the best, as they can see your progress and provide specific tasks to your needs.

However, if you still would like to have a generic training plan not involving an instructor, here are some points which could help in improving yourself:

1. If you don't yet have any musical knowledge, you should learn the basics, such as learning solfege and how to read sheet music. Knowing the basics is important for any kind of musical instrument.

2. Excercise the correct posture for playing a guitar. It is essential to know how to handle it both sitting and standing, as playing the guitar requires having your hand in a position which could feel unusual for a longer period of time. Make sure you can reach all the notes on the neck of the guitar, and make yourself used to it. Beginners tend to relax their hand which is not good for playing music as relaxed fingers will get in the way and can mute notes. Also, keeping a generic posture is required as well for your other hand to freely pluck the strings, as well as getting tension off from your back.

3. If you can comfortably pluck strings and hold down notes with your fingers in the correct posture, you can start trying to play sequential notes. For starters, try out some scales. You can find example training material online, feel free to try out as much as you need, and advance in your own pace. Practice sequential notes several times until you can do it comfortably without error. Don't stress if you can't get something right for the first time, you will get it right in time. Practice is a crucial part.

4. Find sheet music for some songs you like, and which you feel you are comfortable playing. Try playing the song from the sheet music slowly, part by part. Then when you are certain you can play different parts, try playing them sequentially one after another. At the end you will be able to play the whole song. You can start playing it slowly, and when you are confident, you can try playing it on your guitar while playing the song.

These are just vague steps, and they could take different amount of time for each person.
You could also try looking for training videos, or interactive training materials, for example the Rocksmith video game which could add some fun into your lessons.
Good luck with your guitar training!
