The short answer is of course you can! Having a creative hobby or interest later in life has many benefits, surveys show that those who engage in art live longer as it enhances both mental and physical health.
Many of my learners are picking up a paintbrush or pencil after years and years of not having any creative hobby in their lives. The idea that these learners can suddenly learn and know everything is unfair on themselves. Be kind to yourself and allow yourself to make ‘mistakes’ there are really no mistakes in art, only learning. The main thing is not to think about all those younger learners who started earlier but to enjoy the process now.
