In week four:Over the past three weeks, we've given you an insight into the psychological and emotional preparation needed to change: this week we consider what it takes to stay motivated and determined to achieve your goals - whatever they may be. It takes confidence, self-belief and motivation to succeed but the real key to staying on track is knowing that you're not doing it on your own. Via our network of supportive message boards, the iVillage community can help you on your journey.
