Trying to Change Habits

I have been listen to an audio book lately that my friend Jami said was a good book in one of her blogs (yes, I know you said reading it would be better, but I listening to it in my car is the only chance I get for stuff like this).  So far it is a good book.  I am happy to say that I am about three quarters of the way done.  It had a slow start, but now I am at the part that talks about how to change eating habits that have been formed.  I REALLY want to be able to do this.  I have decided to only work or one or two at a time however.  I am trying to replace most of the sugary drinks that I drink with water while trying to also make sure to drink the recommended amount per day (something that a few years ago was not a problem for me).  I am also going to cut chips and french fries out of my diet.  I don't do well with greasy foods anyway.  I am going to work on each of this goals for a month and then hopefully add to them when I am done.  I am not saying that I will never eat chips or french fries again, but I am going to try to teach myself not to eat them in excess.  I think the best way to do this would be to completely cut them out for a little while.  I don't know what I will work on  when I am done with these.  I am just hoping to make myself healthier and not lose steam in the process.
