I recently (re)read The Guide to the Good Life: The Ancient Art of Stoic Joy, which is a fantastic read.
I especially love the introduction, when the author asks not what you want in life (cars, financial success, etc), but what you want out of life.
That’s a difficult question.
However, it’s one worth asking and thinking about, because developing a simple definition of a “Philosophy of Life”, could be as simple asking the following question:
What’s your grand goal of living?
And by this I mean, what is the goal that, above all others, you would not sacrifice for anything else?
