During Harvest Season, You Work The Fields
A generation ago, my family were farmers. Farming can be a hard life, and my grandfather is the definition of tough. Not in a Clint Eastwood way; there were no mean looks or quick quips, instead my grandfather had what I refer to as "grit". He had the backbone and quiet fortitude to stick it out in tough times. He'd wake up at 4:00 am, even when he didn't feel like it.
Stephen Pressfield, in the book "The War of Art," referred to this as being a professional. He said the difference between an amateur and a professional is that the professional does his job even when he doesn't feel like it. Artists, like farmers, know the key to success is pushing through the difficult times even when it's the last thing in the world you want to do.
When it feels like the world is on your shoulders and you're at the breaking point. Just remember to keep it in perspective. Don't let being "busy" stress you out. Stay calm, keep your head down and work through it. During harvest season, you work the fields until you're done.
