I'll tip my hand.
If I tell you something and you say "Wait, let me write that down" I'm going to think you know what you're doing and you're someone I can rely on.
The truth is we all have thousands of things coming our way everyday. To simply say, "I'll remember that" doesn't give me a lot of confidence that you will.
I think if I had to hire 10 people out of 1000, I'd start narrowing it down by the people who write down things they need to remember.
I know you have a lot of techy options available to you. But start writing stuff down and see where it takes you.
