depend on the goal,
1. write down the goal
2. write a specific deadline for the goal and details of the goal
3. set a timeline for small steps to be completed that lead up to the goal
4. continually monitor your progress and mark off each minor milestone you achieve on the way to reaching your goal
5. i would probably tell a close friend or very noisy person about my goal so that they will constantly ask me about it and help keep me accountable for my success
