You've got big ideas. You've gotta get them down fast. That's what this journal is for. Write that shit down ASAP. Dump the contents of your brain on the page. Capture that genie in the bottle
Of course sometimes in the heat of the moment you have ideas you think are great, but once the warm glow of your own brilliance fades, you realise they actually suck. Luckily for you, there's a handy review section on every page so you can go back and mark the ideas that might actually be crap, or perhaps reaffirm you're a fucking genius - it's all up to you.
Now stop reading and start writing. Fucking great ideas don't make themselves happen you know. Write down your idea and what you need to do and learn to make it happen
