That is a good question you have asked. I am an artist and I face the blues (funk) often , regarding everything - art, steemit, people, work. Everything.
With time I have realised that only one thing works. Understanding and accepting the drift and then working around it with a little discipline.

Not too hard. And not too little. Creates the perfect cocktail.
A sabbatical is important . We are not machines. :) . For me, silence music, and doing nothing in the sabbatical, helps.
You need to reconnect with your inner-self to get out of a "funk" :)
