If you’re struggling to know which subs to run maybe this video can help. It’s about becoming your future self.
I recommend his book too. It’s a very good one and there are lots of exercises at the end of each chapter which force you to be honest with yourself. It helped me a lot when I first read it, I nearly completely filled an A4 notepad with hand written notes and exercise answers. I might read through it again at some stage, so this was a good reminder. Although, I definitely did not picture the author looking like that! Not that there’s anything wrong with him, I just imagined someone older when I was reading his book.
The book I read was the same one he held up near the start of the video. It’s called “Personality Isn’t Permanent: Break Free from Self-Limiting Beliefs and Rewrite Your Story”. From memory, I found it a bit gut-wrenching, because it forced me to be honest with myself.
