The best way is to develop and follow a plan. Start with your goals in mind and then work backwards to develop the plan. What steps are required to get you to the goals? Make the plan as detailed as possible. Try to visualize and then plan for, every possible setback. Commit the plan to paper and then keep it with you at all times. Review it regularly and ensure that every step takes you closer to your Vision and Goals. If the plan doesn’t support the vision then change it!
Along with your plans, you should consider developing an action orientation that will keep you motivated to move forward at all times. This requires a little self-discipline, but is a crucial component to achievement of any kind. Before starting any new activity, ask yourself if that activity will move you closer to your goals. If the answer is no, you may want to reconsider doing it at that time.
