You do get really exhausted doing films. You work such long hours, and after a while, things can get out of perspective, just like if anyone's tired, things get on top of them. ↗
Technically, I've been retired for some time now. All I ever do is occasionally write songs for friends, such as one, for a friend who had just turned 80. I wrote a song for him called, The First 80 Years are The Hardest. ↗
There's always an element of fear that you need to work a lot until people get sick and tired of you or finally figure out that you're a fraud after all! ↗
