I’m not kidding. I know everyone has different opinions on things like this, and this is just mine. I’m not qualified to give medical advice, but other than talking to a doctor, I think this is the most important thing you can do to put yourself on a path to success.
I’ll tell you this: if you want to make a change in your life, announce it on Facebook. Then, when you’re having a bad day and think about giving up, you also have to think about all those people who cheered you on, and know they’ll know you’re giving up. If you’re like me, that’ll be enough to keep you going.
Even when I started running, it was going to be a “one-time” thing, just to get me through a day in NYC where I had no access to a gym. I was just looking for a one-hour work out, something more challenging than a walk. Just for that one day, nothing more. And just to do that, I needed EXTENSIVE instructions on how I was going to do it, what I’d be thinking about, how I’d make it a whole hour. I’m talking PAGES of Facebook messages from a very patient friend. It took me an hour to run/walk 3.5 miles, and it never occurred to me that I’d start running. It never occurred to me that I’d fall in love with it.
(and if there’s anything I can do to help you find a place to start, please let me know in the comments!)
