What did you learn last week? Just finished my first week of going full time - here's mine

Last week was pretty huge for me. I'm on a mission to go from £0 - £1000MRR this October with Message Ninja - a chrome extension that generates hyper personalised messages, every time you visit a linkedIn profile Still on £0 right now, but I'm learning insanely quick! Here are some of the key things I learnt: 1. Use your product - you will learn just as much as you do from user interviews 2. If your product isn't useful enough yet, it really helps to take everything back to first principles e.g. - Why am I using the tool? - What do I want to achieve? - What is the simplest solution to this? 3. *you can move so fast* when you are full time, its crazy how much ground I covered in the last week Anyways, let me know what you learnt last week!
