If you are truly creative and let your mind stray without constrictions, you are going to create a shit load of art. It's actually really easy to do. If you're an artist and you experience "writer's block" it means that you are not creating using the right medium.
For example, sometimes I have a lot on my mind and want to podcast. Sometimes after a night of excessive drinking I work on visual art or some sort of manual task. This is how my mind copes with that "block".
The problem is that no matter how much you love doing something, at some point it will become work. If you're a studio musician recording a session and you have to record a line repeatedly, that love is going to turn into a labor.
If you're a touring artist and you have to ride in the tour bus for 14 hours just to play a one hour and thirty minute set, you're not playing music for those 14 hours. How are you filling your time that could be spent creating?
It's okay to take a break or tour and enjoy the process of just being a performer and laying back the rest of the time but this is where the paradox comes in. Do we use our mind to it's fullest potential and continue to grind, create, make mental connections, build businesses, generate more taxable income that could benefit a larger group of people or do we just focus on one road, pave it over and run the same loads up and down it all day long.
That's for you to decide.
