Be humble; Learn from everyone
Learning is a process which we start the moment we are born and it should last until we die. We should regard learning as something great which gives us the opportunity to live a fuller, happier life and to improve ourselves as a person. As an artist you are making yourself and some of the world a happier place with your art work. No matter whether your work will be exhibited or you keep them in your home, it’s a beautiful hobby and a feel-good activity which already makes you a much more content person in all.
Doing arts just for the sake of it is a great idea to start with. Then, if you want to grow, do exhibitions and even try to sell your work when the time comes will totally depend on you. Just walk to the beat of your own drum and make yourself grow as an artist, learn and keep your eyes open to become better and to find the areas where you need improvement and be open to other art styles too.
