I was like this when I first joined the forum...it's been four years so I have calmed a bit and learned to sit my challenge happy arse down. I am a member of several inactive challenges (Drink More Water, Lose Less Hair Detangling, etc.) but they are just reminders of my goals for 2010. For the most part I am happy to say that I have been successful...but that is because they work well with other challenges that I am on (a weight loss challenge which requires me to drink at least two liters of water a day and a personal 2 year C&G challenge).
I have found that challenges for me have to hold to one of my 3 rules to be successful (worthwhile) for me to join:
1) They should be in line with my overall goal. If my overall goal is a personal C&G Challenge, then it's easy to also be successful at a "Hide Your Hair" Challenge and a "Length Retention" Challenge...it's also unnecessary for me to join all of them. So I pick one challenge that is in line with my overall goal (like the Tough C&G Challenge) and join just that one instead.
OR
2) It needs to be something I am slacking on an need motivation to follow through on. I just joined the Sulfur 2011 Challenge. Adding a sulfur application to my regimen is something I have always wanted to do but have been mostly unsuccessful at. I feel as though partaking in this challenge might inspire me to come up with a real regimen and stick to it.
3) I MUST POST A BEGINNING PHOTO! If I do not post a beginning photo because I lack the time, effort or inclination, then I know right away that I will not follow through with the rest of the challenge. I mean, why even bother if you are slacking before you start.
