Have you watched your kids, on school nights, do everything and anything but their homework? You might cajole, nag, threaten, but they continue to find the most creative ways to avoid the books. It's quite possible, too, they learned their best procrastination skills from you! See Apt. 11D - Procrastination So, instead of badgering them, you might want to explore another way.
I too am a procrastinator, but not until I picked up a small book about the subject,(Eat that Frog), did I understand that the things I procrastinated about most were the ones I dreaded the most and which caused me a lot of anxiety.
The title essentially lays out a metaphor that, each day, we all have frogs to eat (big frogs and little frogs), and sets out a challenge for readers “eat" at least one big frog (the source of anxiety) each day. The bigger the frog, the larger the sense of accomplishment, and the easier it becomes to eat smaller frogs. Every day, you need to identify the big, medium and small frogs, and try to summon up a large appetite.
At Think Tutoring we teach study skills to middle and high school students at our learning center, and have recently introduce the Eat That Frog lesson. For all our students, (and parents too), we encourage them to Eat That Frog!
