I'm a self proclaimed perfectionist, so it took me a long time to accept this, but it's true: Success is not about perfection, it's about persistence.
I saw a woman today who hadn't seen me in a long time. She was floored by the change in my body. She asked what I was doing, and of course I told her Weight Watchers. She said she had been on the plan too, but went off. She added that I must be "following it religiously" to have such success.
I told her that No, in fact I do not.
I gave her an overview of my feelings about the plan in general - Don't set yourself up for failure by expecting to follow it 100%. Shoot for 80%. You'll still see results. You simply can't be perfect every day, at every meal. There will be times you don't track, have to guess points, knowingly go over points, binge, don't work out - There are a million things that can go wrong. And they will go wrong. But as I mentioned before, you can't dwell on them. You put it behind you and move on immediately. Get back on track at the next meal or as soon as possible.
The great thing about WW is once you are a member, you know what the right and wrong decisions are. You might not always make the right choice, but you know what the right choice is in any situation. As long as you make the right choices more often than you make the wrong ones, you are on your way to success and will see results.
So do not focus on being perfectly on program at all times- no one can maintain that level. Just be persistent.
