Stage 1: You are anxious about getting a good job, always looking out for a good one which offers (what you consider to be) ‘fulfillment’.
Stage 2: You have been working for a while now, but start getting anxious about making enough money to leave the job and retire, so that you can find ‘fulfillment’ in retirement.
Stage 3: You are now resigned to the fact that you will never make enough money to retire. Paradoxically, you can now stop looking for fulfillment and actually become fulfilled !!
