If you thrive on challenges and hate to be outdone, you may want to find some "friendly competition." By nature, "friendly competition" is not meant to hurt anyone's feelings. It is there to create motivation and to help people reach goals.
There are a number of message boards and forums that are focused on business; you can create a post that explains your goals for the next month and ask other members to reply back with their goals. All of you can keep adding updates each week on what you have accomplished.
You may choose to put together a more formal, tight-knit group of a few selected people that correspond via a yahoo group or private chat room. You can update each other daily, if you wish. You can even take this a step further and meet weekly on a conference call; as it may be easier to discuss problems and brainstorm with each other via telephone.
If you find yourself connecting with one person more so than with the others, ask that person to be your accountability partner. You can even give each other a quick call every morning to pump each other up, or at the end of the day to talk about what you had accomplished and what you plan on doing the next day.
Aside from going over each person's individual goals, you can also create monthly "contests." For instance, if you are in direct sales, you can meet with other people in the industry and have a contest over who can book the most parties, sell the highest dollar amount, or recruit the most people.
If you are an internet marketer, your group can have contests such as who can write and distribute the most articles or press releases. If you create information products, your group can hold a contest over who can develop the most new products in a given month. The possibilities are endless when it comes to creating motivating contests.
The simple fact that you are letting people know your goals, and meeting at designated times to cover your progress, can be very motivating. No one wants to admit that they haven't done anything and that they are not even close to accomplishing their goals. This is especially true if the other people in the group have worked really hard and have accomplished several things.
Knowing that other people are going to hold you accountable for your actions and "kick you in the butt" if you need it, can drive you to work hard and accomplish your goals. However, friendly competition can take a downturn if the competition turns vicious or mean. If you are working at your best level, and attending your meetings makes you feel bad or "not good enough," that group may not be the one for you. Look for a supportive, fun spirited group that inspires you.
