CONGRATULATIONS!!! YOU DID IT!! Not sure what it was but you took the time, made the effort and accomplished your goal and I am extremely Happy for you and Proud of you and you should be too. Take a moment to celebrate your accomplishment but not too much time because there is more to do. However you have to ask yourself the question, What's Next? There is either the next phase of what you just accomplished, something brand new and completely different from what you just accomplished or maybe you have to pick from a list of things that you want to get done. Whatever it is, get to it. As I said, celebrate your accomplishment you've earned.
That brings me to a side note. Don't make your goals/dreams in such huge tasks that you don't see anything completed until the end. If you don't have a few small victories during the process of reaching the larger goal you can get unmotivated. Give yourself something to celebrate so that you can continue to push forward in a positive spirit.
This is short one but I want you to figure out "What is Next" and figure out what the first step you need to take to start on the next part of your goal/dream. Don't stop and be satisfied with the one thing that you have done. There is so much more for you to do, so get to it.
