It’s often helpful to turn ideas about “want you want to do” into descriptions that tell “how will I know when I’m done.”
You might want to “make my website more dynamic”. If your website has 10 pages now you could recast this “want” into a “test” by saying: Every month at least 2 of my ten pages will have some new content.
If the reason you wanted to “make my website more dynamic” was to “attract more visitors to your site, then you can measure the number of visitors each month that your site passes your test (ie, has 2 pages with new content) and see if the number of visitors goes up.
Writing out tests before you start to work on something is a good preparation for being able to go around if you run into difficulties. Writing the test makes you think in terms of “results” rather than thinking in terms of “tools” or some specific actions. Have an explicit statement of results makes it easier to stop and say: “Is there some other way I could reach the results I need to pass my test.”
