Almost everyone has a goal that they want to achieve. It could be something small or something that could take years to achieve. Having a goal is great and knowing how to achieve it is also important. Realizing that there are a number of steps to do in achieve a goal can really help.
In some cases documenting the various steps can help in achieving the overall goal. Also if you end up not achieving the overall goal you can at least see how far you go and even figure out why you didn't achieve the overall goal. For some individuals they don't write down the steps and just plow ahead and get frustrated when they don't achieve a goal because of a major obstacle. At least by writing down the various steps you might discovery the major obstacle before putting a lot of time, energy and maybe even money into something.
For small goals it isn't always necessary to write down all the steps because there isn't lots of steps. At least clearly thinking the goal through can help.
I have goals that I want to achieve and some are small while others are larger goals. There are times when I can't achieve a larger goal but at least having the steps documented I can see how far I actually got. In some cases it has taken years to get back to working on a goal and in some cases the steps have changed.
For me, achieving a goal is done one step at a time.
