Planning to walk

Tomorrow, I plan to walk for at least 30 minutes.  I would like to be able to lose weight and keep it off and walking seems to be the best exercise.  I have gained a lot of weight over the years and the extra weight has taken a toll on my health.  It is time for me to stop being inspired to exercise and just actually do it.  I cannot and don't expect anyone else to do the exercising for me.  I may benefit them but it won't be of any help to not just me, but my overall health.  What really has procrastination and unproductive, inconsistent exercise have done for me?  Nothing.
