This is really easy! All you have to do is get a journal or even any type of notebook and start writing with either a pen, a pencil, or even paint! I love this idea because it's just a way to think back on your life think is important.
and some others were asking about the cursive font people love to write on their notes and journals, so i made a reference page for you to practice with! hope this is helpful! zoom-in for better quality!
