I learned this from Alex Hormozi.

I now have a photo of myself made with one of these make-yourself-old online apps. I printed it out and have it on my desk. I glance at it every now and then when I have a hard action to do. How would 55 year old dalys behave in this situation? What kind of person do I want to become in 20 years?

Plus it freaks out my mom whenever she visits.
