How to ACTUALLY improve your life?

If your work does not align with your philosophy and beliefs, you will be screwed.
If your relationship does not align with your philosophy and beliefs, you will be screwed.
If your routine and daily life does not align with your philosophy and beliefs, you will be screwed.
Figure out what should be your beliefs and philosophy(well it's not gonna be easy), and then align your whole life with it to find true satisfaction.

Note: Beliefs and philosophy is an evolving and hence dynamic entity, so you'd need to make constant effort to align it with aspects of your life.
