Who you are and what you do consistently always coincide. After all, your repeated actions create your identity.
But who you want to be and what you consistently do don’t usually coincide. Otherwise, you would already have become who you want to be.
You want to be a writer, but you’re not consistently writing? Writing consistently will bridge the gap between your current and desired identity.
You want to be a guitar player, but you’re not consistently playing the guitar? Practicing daily will bridge the gap between your current and desired identity.
Could you make your actions coincide with your desired identity?
