Pin a tweet at your Twitter profile.

Visit twitter.com at your laptop, not your phone. Find one of your tweets and then click the downwards pointing arrow at the upper right of it. Pick "Pin to your profile page." from the menu that appears and this will make visitors to your Twitter web presence see this tweet first in the list without regard to chronological order. There is also an "Unpin from profile page." option later (in the same place) for getting rid of this.
