I am a 75 year old 107 licensed drone pilot. I have never really needed the license as my work is recreational but I feel ALL serious pilots should take the test just to understand safety and other issues that can be associated with flying drones. I studied only the FAA online material, l but I would recommend an online or in person course. Now I am learning (by experience, trial-and-error) how to capture and edit drone video. This is my sample video that has integrated 4 trips to a lighthouse over 2 years. I think it takes a 1000 hours to become an expert, but you need to enjoy the learning process each step of the way and just "go for it"! Link to training video:
