Here, I will show you how to make a good blog post/story, LEGO or not.
It always need's a good beginning that will give you some information on what's going on. Example: Jimmy woke up and grabbed coffee, he was tired and fell asleep on the kitchen counter.
Their should be a good medium part of the story for a problem. Example: Jimmy saw his dog running threw to China, he figured out what he could do.
For the ending, it should be the solution. Example: Jimmy called the police and the China Police came 5 Year's later with a dog that didn't look so well.
This is how I make my stories! ;)
