What do you really wish you would have focused on over the past decade or two? (or however long you have been working online). Hindsight is a wonderful thing of course but for me personally, registering quality domains in their early days and the obvious one - studying crypto currencies.

What about you guys?
Not creating good business connections with other people.
Trusting some persons more than enough.
These are my regrets for the past.
