What would you do different if you had to start learning guitar from scratch again

Well I guess the title is self- explanatory.

If you had the knowledge you have now from playing the guitar what would you have done differently or what would you tell a beginner.

I used to play from time to time but would call myself at max a novice player who has quite some theory knowledge. So what would you focus on? Scales? Chords? Dexterity exercises?

I love Rock and Metal. Especially bands like Pink Floyd and Dire Straits. But won’t have too much time practicing because of uni and piano. So what helped you improve the most?
