My hobbie is numerology https://numeroscop.net/free-numerology-report/ , which helps me with many problems. Moreover, numerology gives a clear answer on how to calculate your code by date of birth, for this, the full date of birth is taken - day, month, year and all the numbers are added together.
I personally like crafting a lot, and I often make some cool Custom Lapel Pins using the service from https://www.pinsource.com/ for example. My friends like such things a lot, and I also sell them online. It is a great hobby/small business I guess
