Be Your Own Manager
Whilst being a great musician is important, it isn't always enough when building a career for yourself. Work needs to be done behind the scenes for the project to make progress. If you don't already know someone else to take you on, you'll need to dedicate time to the management tasks yourself.
Jobs that a manager would normally take on include organising band members, booking gigs, booking rehearsal and networking amongst other things. All these tasks can be stressful to juggle along with writing and performing too.
Try and distribute tasks amongst the band where possible. It's important to communicate and be cooperative when it comes to managing these tasks. When someone else is taking on a responsibility, try and support them as much as possible.
If you can all pitch in and successfully run the project on your own, it's one less person to you'll have to pay! However, the right manager will often come with their own connections to help you get bigger and better opportunities, so it's good to be on the look out for someone you can work with.
