When you find yourself procrastinating on your dearest actions, then it is time to really go and find your purpose in life.
If for example your dearest thing is to write and you want to become a writer, like many people dream of, but you just don´t get yourself to write, then ask yourself, why you want to write anyway.
If the answer really electrifies and motivates you into action, then your passion, the writing, is aligned with your purpose in life – to be a writer.
If writing is your passion, but it doesn´t drive you into action then either your purpose in life is not being fully served by your passion (yet), or your Ego and your conditioned mind is taking over with all the old limiting beliefs, fears and back-door-tricks.
To have your passion fueling your purpose you need to decide, what the purpose of your life shall be.
