Don't look at the finish line. It is to far ahead..If you are to busy looking for the finish line you will miss the race.
Take it in small steps. Accept the fact that this will take time, and rememebr the longest journey starts with the first step. Each step takes you that farther to your goal.
Take the baby steps and enjoy yourself. I have made a hobby our of exercise and trying to cook healthy foods. It has made this alot more fun.
