I watched a few of your YouTube videos last night before bed and learned so much. This morning, I randomly picked one of your articles to read, and it made my day start off perfectly. Thank you so much for your work, Lewis.

I'm 29, just finished my masters and am currently travelling while I consider what I want to do next. Your content has really helped me put things into perspective and help understand myself and what I want out of this life much more. Thanks!

I'm about 20 years older than you and am blown away by the grasp you have on concepts that took me decades longer to figure out. Love what you are doing!!! 🫶

You’re saving lives mate, including my own. This was so well thought out and so well put together. It doesn’t insult the intelligence of the audience, and doesn’t devolve into cliches and empty platitudes. You simply give a realistic and firm guide, arming those suffering with the tools required to help themselves out.

I’ve never seen a video so concise with such important information in it. Everyone on earth should be familiar with these principles. What an amazing job you’ve done summarising this.

Hi Lewis, I just wanted to let you know that you really helped me with your videos, I'm 28 years old and it's the first time in my life that I'm feeling like I have my shit together. Thank you so much :)

@Miminaysmn

I'm only 6 minutes in, but I've had to pause twice to try put my exploded brain pieces back together. I seriously appreciate the time and effort you put into making these videos because they're helping me understand myself and others in a way I never thought I would. Thank you Lewis.
