30 minutes rule for a new hobby

Another of my revelations of life, you live, do stuff and eventually you start seeing patterns in everything you do, so this time i noticed one can pick up a new hobby if one just dedicates 30 min a day to that particular thing, i know, i know not everybody has a lot of time and they probably would watch some mindless tv, but for me personally it's more rewarding in creathing something, or doing something new.
