Finding a purpose starts with figuring out what you’re here to do. What do you love doing so much that you would do it even if you weren’t getting paid?
If you apply this way of thinking to your current means of making money and your answer is … ” Oh sh#t, not really “. Then you’ve made a start.
That’s not to say you should up and quit your job, go all in now on some half assed idea you’ve only recently felt passionate about. The transition will happen once you have clearly defined your purpose. You need to start paying close attention to the things you think about, read about and do automatically because there is a pattern there and you want to understand it.
That’s the first step. Pay attention.
