Know that being healthier will improve your overall life--you'll have more energy and feel more accomplished, but also know that it is not the end-all to happiness. Start by knowing you have happiness elsewhere, in fact, mental health should be part of your new lifestyle. So, begin with a pen and journal. Write your short-term and long-term specific goals, and then specific steps you will take daily and weekly to attain those goals. Include mental health things too--such as yoga, meditation, going to art museums, reading positive attitude books or spiritual books, going to a church or charity, joining a reading group, etc. Make your goals and steps realistic!!! Can you spend one hour a day exercising, really? Or, are you the type that if you don't do the whole hour you'll give up entirely? So, how much time really can you spend? Start small, you can always build up! Most success stories I know of start with walking 10 min. a day--walking is physically and mentally healthy and you can go slower or faster, longer, or shorter, and you can do it with a friend, dog, or alone. Each week add something, such as distance, time, or hills, and eventually strength exercises--are you the type who follows dvds, or do you need a trainer? Read exercise dvd reviews on-line before purchasing so you know what you'll be getting. Plan on getting new dvds as time goes on, so you don't get bored and so that your routine changes on your muscles. If walking isn't for you, what is? Dance classes, bike riding, skating, swimming, water aerobics??? Pick things you enjoy doing, not things that feel like a chore. Now, on to food. Be realistic--do not follow or plan a "diet" that includes food you don't like or won't cook. Think of all the healthy foods you like and write them down. Then, think of ways to base your meal plans around those foods. If you don't know how to cook much or you don't know of many veggies and fruits you like, there are tons of healthy recipes on-line or at the library or bookstores. Plan on eating more frequently, smaller portions. This way you don't get too hungry and you keep your metabolism working and you won't feel deprived. Speaking of that, include fundays--maybe a weekend day when you eat the less-healthy stuff, like cake or restaurant meals....to make it a life-long change, it has to be realistic, and most people can enjoy a big fattening dessert or meal every other Saturday night! Plan on documenting your journey--write your feelings, your food intake, and your exercise. Every week or so, review your journal and see what needs to change--more veggies, or less strict meal plan, different exercise, more mental health activities, etc.? Finally, and most importantly, know that it is okay to not be perfect at it! No one is perfect. You mention your fear of failing. Failing at what??? Failing at lunchtime tomorrow? So, if you skip exercise one day or eat what's not part of your plan one time, so what, move on to the next hour! There is no failing, except to never start. Healthy lifestyle really is mental, and creating a balance of mental happiness, physical movement, eating in a way to fulfill our needs, social interaction, pursuit of interests and hobbies, and loving oneself at all times. Take each morning to breath for a moment and say a self-affirming message, and each evening, a grateful statement....something that you have or have done that made you happy and strong and loved or loving that day. Blessings to you.
