Almost every individual goes through moments in their work/life where the weight of expectation is difficult to ignore. Waiting for news following an interview is an example most of us have experienced. Absolute relief only arrives with our answer but some relief can be gained by examining our expectations earlier instead of allowing them to intensify towards a situation with the potential for overwhelming disappointment.
The work/life fusion approach ensures that multiple outcomes are considered. Getting a 'Yes' or a 'No' after interview creates a distinct fork in the road. If successful your immediate future lies with your new employer. If unsuccessful your research continues but with the addition of new lessons that can be incorporated into future decision making and opportunity management.
It would be wrong to suggest that work/life fusion can provide immunity from disappointment. What it can achieve however is a mindset that values every experience along the road to personal success and a better chance of managing expectations rather than expectations managing us.
