Sometimes it can be difficult to get down to your studies because you have distractions to deal with, and you may find that you put off a study task. Distractions can be real (e.g. your child needs your attention), but they can also be displacement or replacement activities, or ways of procrastinating in disguise.
Some people say that they need the pressure of a tight deadline to get on with, say, writing an assignment. Ask yourself whether this way of working is really effective or whether it is disguised procrastination. You might find you produce better work under less stress.
