4 years ago today I went to work with some odd queasiness but shrugged it off as nerves since my family was getting ready to fly out to visit Japan. 4 hours later I finally gave up and went to the Doctor to find out my "queasiness" was a heart attack. Spend the next 3 days in the hospital, had 3" of mesh tubing put in my heart to keep it working, and needless to say.. had to cancel our trip to Japan.
Since then, I have kept on the track I was already on and finished both my Bachelors and Masters degrees in Social Work.
Pay attention to your body, know your limits, and never quit, no matter what life throws at you.
