To be successful as an artist you need to be absolutely passionate and willing to work hard. An artists is always an artist, you do not put your hat down at the end of the day and switch off. It is an advantage to have some talent, but a lifelong willingness to grow and learn
is much more important. If you are an idealist refusing to consider the possible commercial aspects of your work, you might still be successful, but only if you have a unique talent or an immense amount of good luck.
