Making the effort

I got a wake up call today when I went to Cranbrook for a walk with my friend Jenny. We went from garden to garden and I was out of breath and it was hard for me to walk after a while and also how out of shape I am. Now I need to get myself in gear and wake up, have breakfast and go for a walk for 15 minutes. I need to set a routine so that I can follow it every day and make a EFFORT to stick to a plan and lose this weight. I don't know what my problem is. Why can I follow through at something (such as weight loss) and finally lose this weight. I hope I can find a way to stop this cycle of thinking and just get to a plan that will work.
