To be a successful creative you have to make the time and do the hard work first.
The artist who works long hours in the day just to pay the bills still comes home at night and paints until she can’t keep her eyes open. The writer who has a family to look after does the work required to help them be happy and healthy and then writes from 1 am until 3 am each day in pursuit of his passion.
It’s the same story for entrepreneurs, designers, illustrators, film makers, photographers, craftspeople, and anyone else who creates.
You can come up with all of the excuses in the world for why you don’t have time to do creative work, but then you’ll be just like everyone else: unsuccessful at pursuing your creative endeavors. If you really want to be successful, you’ll do what it takes to reach that point.
