I wish I had coined the phrase 'tyranny of choice ' but someone beat me to it. The counterintuitive truth is that have an abundance of options does not make you feel privileged and indulged too many options make you feel like all of them are wrong and that you are wrong if you choose any of them.
I am fussy about my diet and straining my voice. I know sounds a bit over the top. But I'm not as bad as I used to be. These days I don't drink alcohol for five days before a show - very dehydrating for the vocal cords and all that acid reflux. I used to ban it for a fortnight. Nightmare.
