Is it true that most successful artists start at a really young age, like 1 or 2 years old, and so by age 18 have nearly 15 years of practice under their belts? Not to mention that as a child they had no job or responsibility so could dedicate 100% of their time to art.
So for an adult beginner with a job and a family, etc it is pretty much IMPOSSIBLE to put in enough time to get good. It's already over, they will never succeed unless somehow they win the lottery and can lock themselves up for the next 15 years to practice art.
But even if they did that, it would mean debuting at like 65 years old. How could a 65 year old newbie artist hope to complete with younger established artists on social media? And their hands would be arthritic and would only have a couple of years to produce work before old age takes it away.
I'm really becoming galvanized of the opinion that if you haven't found success by age 20, you will never will.
