It's easy! You can create a tag while you're typing your dones in your email or in your online calendar.
Here's how:
Type your Done, Goal or Blocker.
At the end of your sentence, just type # followed by the tag you wish to create. Don't leave any space between the "#" and the words. For example, "#sales" or "#spaceexploration."
I Done This will automatically turn your #word into a clickable tag.
Just use the same tag again whenever you get something done in the same category.
