Sometimes you just have to not go forward. But when it’s something you love to do; doesn’t that mean something is wrong. Yes, it means that the time is wrong. But can’t you push through. Yes, but will you end up with the truest expression or will you end up just finished. You have to take a quick inventory of your energies and experiences in the past, then determine whether to push, but when you know, why not relax and gather your energies for a dance with the muse.
If you want to push; spend the time practicing a new technique or learning something new. Or give yourself permission to vegetate.
