Many times, stress is created artificially. It hurts our performance and deteriorates our ability to think.
Encountered numerous situations where work was "urgent" and would likely land a contract or sales for the company, and everyone would be a superstar if they delivered this "crunch".
After 2 months of pulling all-nighters and sleeping for 3/4 hours, we deliver the project ahead of time. Apathy begins to set in after management/decision makers keep on giving these gifts we call "crunches".
To help the company and go the extra mile is something most of us have done in the past and will possibly do in the future. However, it's like the story of the boy who cried wolf, if everything is urgent and every task is to be done NOW, then there are bigger issues at play.
Like everything in life, there is usually a limit/budget of money, time and effort. By abusing these limits and tolerances, people will lose respect for the people crying wolf and will put less effort into their work.
