Lesson learned: Have support.
Having support during your weight loss journey is huge. And I probably couldn't have done as well as I have without the support of my husband. Because he was as committed as I was.
Once you embark, I'd suggest finding one or two people to be your cheerleaders: someone who really believes in you and supports your health and well being. There are certainly times where I don't feel motivated or I feel like I haven't made any progress. Being able to talk about that with someone helped me get past those challenging points and helped me stay focused on my goal.
I also found I needed someone who would hold me accontable for my actions. I didn't want someone to stand over my shoulder and tell me, you shouldn't eat that. I can do that just fine in my own head! What really needed was someone checking in every now and then to see how I was doing.
When looking for support among your family and peers, let them know what you're doing. Tell them why its important to you. If they are the type of person who is always tempting you into trying the new burger or ice cream place, or is always bringing pastries to your desk, let them know you appreciate their jesture but that you're on a journey and need their support. I've found that by asking them for help or to be your cheer leader, they're usually willing to leave those not-so-healthy habits behind.
If you're having trouble finding that person or people, how about this web site? I'm happy to stand on the sidelines and cheer you on! And I'm guessing there are lots of other people here too that are willing to do the same. It's a community after all, and we're in this together!
