this is seriously a “by basis” question. Someone who is wanting to be an Yngwie Malmsteen is not going to be in the same spot after a year as someone who just wants to be like Kurt Cobain. Also, we have to take it into consideration a lot of other factors.
1. Does aspiring Yngwie guy have a supportive family who bought him his first guitar and paid for his lessons while aspiring Kurt guy struggles with depression and can’t focus on guitar because his family is always fighting?
2. Does Yngwie guy get to sit at home all day and play guitar while the aspiring Kurt has to go out and work 50 hours a week to support his family because his dad left his mom and his mom is sick on disability?
3. Does aspiring Yngwie pick up on things easily while aspiring Kurt struggles with rhythm and can’t grasp the concept of chord changes?
This is NOT a race. You shouldn’t be at any specific spot in anywhere in your journey after any length of time. You are exactly where you’re meant to be given your situations. If you want to be further, work harder. Simple as that
