It’s easy to underestimate the time it takes to do something. Booking hotel rooms should be easy. What’s your budget? Where? This hotel is closer to the venue but further from the airport (and the plane that lands at midnight). Eventually, you have to book a hotel room--but it might take a while to get there. Leave yourself time to make good decisions, especially for logistics and marketing.
Does your project not seem real to you? Try doing something tangible to move it forward. Planning, making spreadsheets, budgeting, building a website are vital steps, but they also don’t create something you can touch. Contact the venue or the musicians. Put money down--or do something that puts you on the hook. You’ll feel the responsibility--and the corresponding sense of realness.
Sometimes, you just have to move on from a project. It’s not working for some reason. There’s no sense in spending more time and money on something just because you’ve already spent time and money (the sunk cost fallacy). Maybe you were desperate to make it work--it’s your passion project. Think about why it’s not working. If you can find a way to move it forward, great. If you can’t, set it aside--at least for now. We can always return to our old projects with a fresh mind.
If you could do anything, what would it be? Would it be the same thing that you’re doing now? We might not be able to do what we want to the same degree if we had a ton of money or time. But we can do what we want to a lesser degree--proportional to the amount of time and money we do have. Why wait to start doing what you want?
