What made me do it was a change of perspective. I was really kind of mad that my 20 year old self didn't do it. I thought I was too old at that point. But then I followed that logic, and my 60 year old self would likely be just as angry at me for not doing it. I was never going to stop feeling this way. I couldn't change the past, but I could change the future. There would never be a good time to do it. I may as well get it done today.
As it turned out, it was the perfect time for me to do it. The pandemic lockdown made the early years so much easier. But I didn't know that was coming.
