Last minute rush.
When we are faced with a last-minute rush, we buckle up and try to get the work done somehow before it's too late.
We work late nights and weekends and whatnot and there is a heroic feeling when it all gets done.
What we skip mostly, though, is the introspection into why this situation came into being and how we can avoid it happening again in the future.
Given, that some people thrive in this last-minute panic environment, but it does take a toll on our physical and mental health.
The alternative is to plan keeping slack in mind, setting deadlines assuming we might take twice the time we expect the assignment to take and some more.
A student who comes to the class much before it starts has a completely different state of mind than the one who is getting late.
