frustration of purpose

Frustration of purpose occurs when an unforeseen event undermines a party's principal purpose for entering into a contract, and both parties knew of this principal purpose at the time the contract was made. Despite frequently arising as a result of government action, any third party (or even nature) can frustrate a contracting party's primary purpose for entering into the contract. (source: Wikipedia)

while there is no enforceable contract between me, myself and I, i did make a commitment to exercise regularly. there has been much frustration of my purpose over the last seven months. first, the fringe edges of Hurricane Irene fried the treadmill. then, i had to go and find some source of income during most of my daylight hours. now, mother nature gave us a teensy bit of snow covered with a layer of slippery sleet on a weekend. 

even buddy was moving slightly more cautiously on the crunchy winter mess. i'm terrified of slipping on ice, so i'm hoping tomorrow will be just warm enough and without more precipitation that i can get out and run in the afternoon. then it's back to the salt mines. the temp assignment is going well. the studying comes in waves. i'm getting it done, but i'm tired all the time. i question my choice to take this exam one more time. i keep plugging away. twenty-five or thirty-three questions during lunch hours. lectures five evenings of seven. locating, reviewing, reorganizing, refining existing outlines. procrastinating on practice essays. lather. rinse. repeat. five more weeks. i can do this. i want to do this. i will do this.
