To accomplish your goals, however, you need to know how to set them. You can't simply say, I want and expect it to happen. Goal setting is a process that starts with careful consideration of what you want to achieve, and ends with a lot of hard work to actually do it. In between there are some very well defined steps that transcend the specifics of each goal. Knowing these steps will allow you to formulate goals that you can accomplish.
How to Set a Goal. First consider what you want to achieve, and then commit to it. Set SMART (specific, measureable, attainable, relevant and time-bound) goals that motivate you and write them down to make them feel tangible. Then plan the steps you must take to realize your goal, and cross off each one as you work through them.
