A passing thought:
Putting things off or cramming in, may be adding to stress. Sometimes we hold back on things, either because we can’t be bothered to finish a job off, or we work better under pressure and know that if we start the job too soon we’ll perhaps not do as good a job, as if we started the job near to our deadline. Some of us work better under pressure.
Some of us do better because we start and finish our jobs in good time. However, you meet your deadlines, just take the stress out of how you meet your deadline. Of course, how you choose to meet your deadline is up to you.
