I hope this helps. I've been using this technique since I've been competing in writing competitions:
First, sequence what would happen in three main events. Beginning, Conflict, and Ending. After you've sort all of the three, sequence the events what would happen in those category. And when you have sorted them out, do the finer details.
Which is what happens on this and that, should you put a cliffhanger on this and that. And if you can't control the ideas coming in to you, just write them. And sort them later to which part of the big three (Beginning, Conflict, Ending) would you like them to appear to.
And if you're ever writing a novel, well for me, it was ideal to make the characters and places first. Then sort out the whole plot by chapters. It's always great to plot the draft of the chapters first before you thoroughly write them. In short make a guide for what would happen in that chapter.
And this always work with stories, articles etc. To catch the reader's attention, give them the most intriguing first sentence you could pull off, or the first paragraph. Something like:
Tall, dark, and handsome. Those were the qualities I was looking for a man. Who would have thought he would walk in front of me in this chilly day. He made my heart skip a beat, and thus I embarked on a journey to meet who he is.
