first off....CONGRAT S to you for returning to school in addition to all your current responsibiliti es.
to be totally honest, and i'm not attacking you personally here ok..... at the rate that you are going, you will get burnt out FAST. there will come a time when you are going to crash because as humans, without a sense of balance we get knocked off our feet easily. i seriously urge you to STOP, REFLECT, and take TIME for yourself to figure out that balance. i too have let go of the tidiness of my home, sometimes i don't do the dishes because i have an exam to study for or even snap at my kids many a time because i lack the quietness in my home to study. you on the other hand, do have a hubby. before you burn out, ask your hubby to assist you in creating balance not only in your academic goals but also his help in your personal goals.
i know you probably have so much reading up your arse, however a book that i have found to be so helpful and meaningful (it assisted in restoring balance to my life) is FIRST THINGS FIRST, authored by Covey,Roger and Merrill. it really makes you stop and really assess the important things from the critical things in your life. i highly recommend this book!
i applaud you for not wanting anything less than a B! we all want to get the highest grade, however make note that sometimes in life a C is ok too. just don't make it a habit or lose sight of what's important in life by only focusing on that A in school.
i was in similar situation like yours....and now after many years, the light at the end of the tunnel is near:) White Lotus, you too will make it....i just know it!
