<3 I have no real psychological reason, I just know that being bored or in a lull is part of our creative process :-) It's when your brain is mulling over and over and over on something, which seems unproductive, but in fact it isn't. Watching Netflix, clicking random links on the internet, reading a book... It's okay - we create not always by being productive, but also though being bored and feeling passive from time to time :-)
Cheers Tom, you'll get back, I know you do - you have so many stories to tell still! Just not today <3
