If it's your to do list you can do that in your laptop and then split the page into 2 columns. I draw a box around the second column (on right) and print it out.
I start with a regular Word monthly calendar where I list all to do's and bold to prioritize for that day (or change the color). Then in a separate document, weekly (Monday through Sunday) I make a 2 column document and draw a blank box around the blank right hand column.
Then I print and staple it. Later I put it in a 3 ring binder. I carry 2 different color pens (green and purple or blue) plus a highlighter and carry the weekly calendar.
In there, I take notes on the Word list on left and write achievements, accomplishments, what happened on the right.
You can also buy a calendar. I like the ability and flexibility of Word because I can insert journal pages between calendar pages.
Alternatively you can buy a notepad, ideally one that means something to you, or one you bought from a special place. Label the notepads and put them somewhere meaningful.
You could also voice record them and save them as computer files. Not as sentimental, but they’ll remain forever
