Stress - the urge or tension that we felt. We usually feel the stress when we have deadline to meet, or task that has zero tolerance of getting wrong.

Working under these constrain firstly results in a highly focused and very efficient work mode. But when the period of tense is prolonged, it's not only efficiency drops, but also the motivation gets diminished.

That's why setting realistic schedule and priority is so important. But they are usually skipped or poorly done. Lack of time and over ambitious are usually the cause. Ambitious, desire to be a hero or simply don't want to be looked down as obstacle are what leads to un-realistic schedule.

Be honest to oneself, and also to the decision are keys to reduce the un-necessary stress. Get the whole team involved instead of taking it all over by oneself, there's nothing must be done by YOU.
