Step 1: send yourself a message and mark it as Saved. It will now show up in your Saved items. The message should contain a section for what you did yesterday and what you're going to do today. Other than that it can be any content or formatting you like.
Step 2: set up a channel for posting your daily logs, e.g. #yesterdayandtoday
Step 3: update your daily log (saved message) as you go through your day. Add things you did TODAY in the Yesterday section, add things you know you have to do TOMORROW in the Tomorrow section.
Step 4: At the start of each day, copy-paste your saved message into the daily logs channel. Do this every day, this will form the longevity of your logs.
Finally, to review all your logs, just search for your name in the channel. Or tags, or whatever. I like to divide my log entries between tasks, accomplishments, blockers, and goals.
