I had a heart attack in January and I set a couple of goals for myself to prevent that from happening again. First I decided I needed to lose weight to the tune of around 100lbs. Secondly, I needed to get my credit cards (and subsequent medical bills) paid off to help reduce my stress. Finally, I set a goal that I'd like to run a marathon.
Since then I've lost 38lbs, only have three more months until all my credit card and medical debts are paid off (especially tough since I got a $15,000 bill from the heart attack and subsequent follow-up), and I'm training up to run a marathon which I might be doing in September.
Although I might have to settle for just doing three half-marathons (I'm already signed up for two) because I'm still a bit overweight and my doctor says I shouldn't push myself.
