If I were to give one piece of advice to someone, it would be to take photos of everything. The people you love, the things you love, the things you do. There will be times in your life when you want to surface forgotten memories on command, and photos and video are perfect for that.

I wish I could also recommend to categorise images as you take them but that is a waste of life. I spent hours looking over the last ten years of my life this week, and it's so strange to view that amount of time compressed like that. The points in your life that overlap chronologically but not in your head, are quite interesting.

Also, be careful with rsync --delete. I lost years of photos to reckless use of that command and it haunts me 13 years later.
