Do it now while:
- You have the motivation
- And the context is fresh in your mind
If you repeatedly "do it now," you'll get so much more done.
Otherwise, the todos will build up in your todo list, for you to organize but never do.
- Be more reliable for your team at work, by doing the little things immediately.
- Keep your house tidy by putting things away & cleaning things immediately.
Do it now. You could also collect todos, tag them as quick, figure out their next actions and batch them to do on a Friday. But that doesn't work as often as you think.
So it's best to do it now.
