Most of my colleagues talk about how it is difficult to get started with a story sometimes. Or even build an introduction that ties together the rest of your copy perfectly. Here are some tactics I've used that I hope are useful to you as well:
1. Throw out an element of shock that immediately gets the reader hooked.
2. Use an analogy to help readers understand the similarity and relate to the story.
3. A play on words is always great, also a sign of a true crafty wordsmith.
4. Repetition. This one should be used carefully, or it will reek redundancy.
5. Include one truly memorable word that piques interest.
6. Introduce an element of mystery to encourage reading on.
7. This one's simple - a question or a declaration leading into your piece.
8. Address something that is a universal concern like love, money, sex, food, work.
9. Another often observed trick - a pithy quote.
10. Keeping it simple and memorable. Don't unload a barrage of technical terms or hifalutin phrases all at once at the very beginning - readers will turn away!
