  • Work it

Kirby also brought out his own thoughts – drop down every ideas you have in mind – You mind is not always as good as paper and sometimes it only stays for a short period of time. After you’ve dropped your ideas into your notepad, you will also have extra chances of linking and modifying your ideas together.
