Be realistic .

You can’t possibly get through life without making mistakes.
One doughnut doesn’t a diet ruin. Remind yourself of your goal,
forgive yourself for the minor slip, and resume your diet.

An alternative to all-or-nothing
thinking is both–and reasoning. You need to mentally allow two seeming
opposites to exist together. You can both succeed in your overall educational
goals and fail a test or two. Life is not a case of being either a success
or a failure. You can both assume that you’re an okay person as you
are and strive to change

All-or-nothing thinking can sabotage goal-directed behaviour. You’re far more
likely to throw in the towel at the first sign of something blocking your goal
when you refuse to allow a margin for error. Beware of ‘either/or’ statements
and global labels such as ‘good’ and ‘bad’ or ‘success’ and ‘failure’. Neither
people nor life situations are often that cut and dry.
