One day I'm super into boxing, the next I'm buying a bike. I'm writing 1/4 of a screenplay, I'm learning to make 4-5 fancy cocktails. I'm ordering a jump rope, a kendama, a yo-yo. I'm attempting to learn tennis by hitting a ball against a wall for half an hour (once).
Picking up hobbies and then dropping them after a few tries is nothing to be ashamed of. It should not discourage you for fear of being called a quitter or flippant. The secret is knowing that you're better for getting out there and ceaselessly pursuing further opportunities for joy in your life.
