We think. All the time. Your brain runs a gazillion thoughts every day. You know those thoughts that come to you and you’re like “oh my god I need to remember this, it’s amazing!” Chances are you’ll forget it. Your brain tends to forget easily, especially thoughts that come to you. Never leave it up to remembering it, because you trust your mind to be smart enough to save it.
Always write your thoughts down, even if it’s really random. If you think it’s worth remembering, it worth a jot. Just take a stack of Post-its (try the ‘notes’ function on your phone, finally you can realise its worth) and keep it for your winning ideas and thoughts, you never know when they can come in hand. It’ll be with you forever
