‘Being ready’ is an illusion because there’s always more you can learn… how much knowledge and information does a person really need before they’re ‘ready?’
I dreamt of playing like Mark King in front of thousands of people, even though I’d never picked up a bass before. I first saw him play on TV back in the day and with my internal mind I pointing to the screen and screamed ‘I want to do THAT!’ even though I’d never seen anything like it before.
I don’t remember learning to ‘slap’ bass, I just started doing it and before I knew what it was all about I just started playing in bands.
I don’t ever remember thinking I’m not good enough, I don’t know enough or I’m not ready yet.
I was too busy doing it.
Consider the idea you know enough about your ‘thing’ already and are good enough today.
When you do the thing you want to do because you want to do it, you’ll find you enjoy doing it and you’ll do your best work.
