Workshops teach techniques. Every workshop instructor will have their own method of painting. So you might be taught to never do ‘this’ in one workshop, and to absolutely do it in another.
Art has no rules. Anything can be ‘right’ or ‘wrong’, often only depending on timing or intention.
There is too much talk about ‘best painter’, ‘master painter’, this and that. People being put on pedestals, like they’re deities. If you classify people you create hierarchies and that creates suffering.
Looking for validation outside yourself is tricky business. If you try to paint like so and so, you’re setting yourself up to suffer because you’re not so and so.
Same thing happens if you’re painting to be ‘liked’. It is certainly good to get validation from your peers (notice I did not say followers) but not if you’re painting to impress someone or to get into competitions. Again, you’re setting yourself up for suffering! Be mindful of your motivations. Look inside of you for guidance.
I’d love to quote my favorite poet here when asked by a student if his work is good or not:
‘A work of art is good if it has grown out of necessity. In this manner of its origin lies its true estimate and value: there is no other.’
Rainer Maria Rilke (Letters to a Young Poet)
In other words, it comes from a deeper place inside you. You have to paint, you have no choice! You will find subject matter that moves you, because what you love you’ll paint better. You need to express yourself that way and that in turn makes your art real.
