That moment when you when you finally get what you wanted to work

So after weeks of just sitting there in front of looking at Dreamweaver and trying to code a drop down menu. At some point of sitting there coding it just finally worked. I am still trying figure what exactly I did differently but I got the code to drop down menu to work without using any of dreamweaver spry things or the widgets that are available to use. But has anyone else came across that moment when things just worked finally?
