Meditations 4. 12. shows two ways to find purpose through two guiding principles. The first is to act in the principle of doing what is right for mankind. The second is if you change purpose in life to have someone to guide you like a mentor or teacher. Whatever actions are taken it is to be taken with the idea of the common benefit. But this may not be a popular viewpoint to have. Acting with a purpose means being true to ourselves. The only way of finding your true purpose in life is by refusing to live a life that isn’t centered on getting approval from other people.
