I have a daily diary I've kept for 6 years. It's just bullet points but everyday I can see what I did 30 days ago and the same date every year. I think that's helped reinforce those memories. That strengthening of memories ideas has lead me to think I should do the same for everything I learn. Just quick bullet points I'm reminded of later. But I've never done it mostly because it would be too taxing. I often fill in what I did 3 days later not on the day and remembering what I learnt 3 days ago is even harder than remembering what I did. I've meant to try and build a habit like making a quick note everytime I go to the toilet or have a drink but again, haven't managed it yet.
