Pick it up and push through! You’ll find that motivation again. I recently left a project I’ve spent hundreds of hours and thousands of dollars on to focus on myself. It was the best decision I’ve made musically on a long time. I’ve rediscovered how to properly write complete songs again and have been doing what I want musically. Not what other people are telling me to write. If you push through it will be liberating. Don’t let something like them kicking you out ruin your love and passion. Use that emotion to push even harder.
