I just wanted to send a quick note and say WELCOME! You will probably get several. I have been on Spark for a few months now but haven't been using it to its full potential. I too am almost 40. I will be 40 in June 2012. I have a goal to be "FIT AT 40" I completely get your feelings of not wanting to fail AGAIN! One of the things I am just coming to terms with is that you get what you give. On the weeks I watch what I am eating and I drink my water and do my walking I am successful. On the weeks that I drink soda, and watch TV I feel sluggish and never drop a pound.
I encourage you to read as many postings, blogs, news letters as you can stand lol. You never know when someone is going to say what you need to hear.
Here's to your success! I am here anytime if you want to just chat. Take a minute and read all about me if you wish!
