Have a strategy.
Your strategy is all about setting yourself up for success by creating the right environment. You need to create a strategy of ensuring you reach your goals. Your strategy includes things such as defining who is in your support network, how will you track your progress, what will you do to maintain motivation when you start to see it drift, where/who can you learn from and what other resources can help you in achieving your goal.
Your strategy is your tool for helping you stay on track for reaching your goals.
