Doing something as part of group can increase your chance of success. Although this might seem obvious to some, we know that many things that seem obvious are shown not to be effective when they are carefully tested. This example, released today, showed that people were more successful in increasing their fruit and vegetable intake when they were part of a 4-person online group, compared to tracking their fruit and vegetable consumption on their own. The study also showed that people were less successful in increasing their consumption if the other people in the group were doing much better than they were. This means that you might do better working with a group with which you are more likely to keep pace. Not always easy to predict beforehand, I know, but better than going it alone.
