"Paint what you like and die happy."
— Henry Miller
American Novelist, Painter
1891 - 1980
The message here is simple and direct: do what you like. Too often we don't do what we like. Nor do we learn to like what we do. And then people become unhappy with their lives and they spend their time complaining. Don't let others dictate what is important for you.
And I am not telling you to run away from your spouse and children and join an artist colony where you spend every day either painting or writing. We all have responsibilities and we should not shirk them. If you get married, you have made a commitment and you need to live up to it. If you bring children into this world, you have a responsibility to raise, educate and care for them. Doing what you love does not mean avoiding your responsibilities. Doing what you love means finding 30 minutes or 60 minutes where you do what you want to do — where you do what you love to do. Then you can die happy.
