There are two ways to approach your goals: You can be flexible, and let the next steps evolve as you work toward your objective, or you can be rigid, and set specific actions to take. To decide which approach you should use, ask yourself how difficult your goal will be to achieve, how invested you are in achieving it, and what else you have on your plate. In situations where your goal is relatively simple and you’re highly motivated to achieve it, a flexible approach typically works best. In situations where the change required is difficult and you feel less engaged, lay out a firm sequence of steps. And be mindful of your track record. If you struggle with follow-through, or you find that there are simply too many priorities competing for your attention, you’ll need a rigid approach to pursuing your goal.
