In books, movies, and daily conversations, you may encounter phrases of wisdom that you want to keep in your mind. There is a good way.
Make a special List named [Cookies], for example, and write the phrase as a task in the list. In order to distinguish it from other tasks, put [cookies] at the top of the task name. Then set it to repeat every XX days. If XX is enough long such as 88 days, for example, you may read the beautiful phrase that you have almost forgotten, as if a long lost friend.

Here are examples of my favorite cookies that I picked from in-flight movies.

[cookie] Everything will be all right in the end. If it's not all right, it is not yet the end.

[cookie] The world is a playground. You know that when you are a kid but somewhere along the way, everyone forgets it.

In a few years ago, when programmers were using dumb terminals, fortune cookie was a very popular command automatically executed when they log-in/off UNIX. Bob may know it.
