Whatever you’re setting out to accomplish, the best thing you can do for your career is finish your music projects and bring your ideas through to completion.
This might be the simplest and most valuable piece of career advice I can give you: Finish things! It doesn’t matter what those “things” are: maybe they’re songs, an album, a music video, booking a tour, a crowd funding campaign, a new website, or new merch designs. Whatever they are, the best thing you can do for your career is get in the habit of finishing your music projects and bringing your ideas through to completion.
The problem with perfect
I see so many musicians sitting on their ideas, songs, and projects for months (sometimes years). They keep refining and editing, trying to improve their product because they feel like it needs to be absolutely perfect.
