What's that mean: 'i walk slowly but i never walk backward'.?

It means that my progress is slow but I never stop progressing

In regarss to the speech first, I would include simple but funny stories to include in my speech. The speech should be well written and mad to make the audience laugh. The night before, practice the speech in front of the mirror or in front of a couple of friends. For the video presentation, add pictures related to the bride and groom. Add music thats easy to the ears and make the presentation work with the wedding color scheme. The night before, practice your speech so you dont forget it when it comes time to deliver it.
