Side Projects are important.
For me, the best way to make ideas happen is to start them as side projects. That way they don’t have to provide you with a living. You can still eat if they fail. They don’t have a deadline. And, as there is no time pressure, you don’t revert to your usual formula. You try new things. You experiment. You give them time just to play around for a while.
They are what you call a Labour of Love. You provide the ‘Labour’. It provides you with the ‘Love’. The thing I have noticed is that side projects have a happy habit of becoming your main project.
So select your side projects well.
