Took my nephew to his soccer class. The class next to his took a water break. One kid came running out yelling "We won! We won!". They had been working on drills.
What's your enthusiasm like toward your entertainment career? Are you only excited about bookings and award nominations? Or are you like that kid who won soccer drills?
Look at anything that progresses your career as a success to be celebrated. Get current headshots? Great. Find a good class to work on an area your weak? Great.
Of course, booking a recurring role calls for bigger celebration than adding a comedic monologue to your acting bag. But if your not enjoying the journey, you will never arrive at the destination.
