Just do it. There won't be a day where you say to yourself "Hey, I'm ready to make this album"
That day doesn't exist because you will always feel like you can get better, and your standards for yourself will always increase as you become more skilled.
Start writing now, and take what you wrote to heart -
"not having any one opinion being wrong or right"
that means even YOUR opinions should be thrown out the window.
Start now!
