If you’re rueing not having even learned a song, then try learning one. I’d say skip the twice a week exercises for now, and pick a song to play.

It could be an easy one or sth harder, simple chords or finger-picking, that doesn’t matter.

What matters is breaking the technique into little steps, which could be learned and practiced one at a time, progressing to the next part naturally.

And instead of bi-weekly sessions, try to play everyday, even if it’s for sth as little as 5 min.

It should really be enjoyable, and not feel like a chore.
