Capturing and processing
Processing means taking each item out of your Inbox and deciding what it is. It does not mean doing everything. Aim to leave the Inbox empty, with every item in a trusted place.
If you are not ready to decide about an item, choose Save and leave in Inbox to keep your notes, or Skip for now to come back to it later.
Process your Inbox at least once a day, and as step 1 of the Weekly Review. A short, regular pass is easier than a long, occasional one.
