The best way to stay motivated is to love yourself. I know this is hard for many but it can be accomplished. Stop the negative self-talk now. When you catch yourself thinking or saying something negative about yourself, stop and make yourself say something you like about yourself. You can break this habit and create a more positive one in its place!
Don't ever let other people or worse, your negative views of yourself cause you to be sad and depressed. Completely ignore what others say and always give yourself reasons to love and value you, no matter where you are in your journey.
Wear clothes that are becoming, no matter what size you are. Choose colors that compliment you and features that hide flaws and highlight assets. Don't stuff yourself into too small clothes. As you lose, chose more fitted clothes that will help you gauge your progress and motivate you to keep the weight and inches off. At some point, a belt will become an accessory!
I make it a PRIMARY goal to NOT give myself any negative messages about my body: what it looks like, how much fat it's carrying, whether it seems bigger or smaller on a given day. I firmly believe that a body can only change from a place of love and acceptance...and if I can't conjure love and acceptance, then I at LEAST don't let myself descend into negativity. If I find myself feeling fat or ugly, I tell myself, "That's how I feel at this one moment. This moment is not forever."
I was unhappy with the time I was spending in my workouts - For weeks I felt disappointed if I wasn't doing 2 hour workouts - I have the time and resources - so no matter how much time I did do, it was always as though I could always do more. Today I reset my fitness goals, joined a group that only requires 30 minutes of cardio and 1 video per day. I know that setting this more realistic goal now when I go 5 - 10 min over I can celebrate an additional victory - these will boost my self esteem.
My depression makes self worth & motivation a challenge. I try to ignore my negative thoughts. I talk frankly with my 7 yr old about how bad obesity feels and why people need to be healthy - healthy, not skinny. I fake motivation when it's gone. I applaud the tiniest success and forgive my failings.
I keep a list (mental and actual) of songs that make me feel good about myself. If I'm having an "ugly" day, I put them on while I get washed and dressed, and before I know it, I'm dancing, singing, and feeling better. This week's favorite: "I Look Good" by Chalie Boy
You wouldn't tell your best friend that she is fat or ugly or worthless, so don't say it to yourself! Tell yourself you are beautiful, with or without the extra weight. You are the same wonderful person regardless of what you weigh. Weight and Worth are separate.
