So, surround yourself with people, tools and activities that make it more likely
for you to succeed than to fail! Arrange your living environment and social situations so that every thing around you pulls your forward, instead of possibly leaving you totally de-motivated.
Use Your Resources.
Read motivational tips, general health information and any other literature you can get your hands-on. Information is power!
NOW TAKE THE FIRST STEP
There you have it. So you can get started today, and make sure your whole approach is controlled, rational and methodical. If you can take the "long term view," and set yourself realistic "achievable" goals you will most surely succeed.
