How about
:
1. Steelhead and salmon flies e.g. Intruders, Popsicles, etc
2. Join some fly swaps and let them dictate what you are tying.

3. Select a fly and tie up all the variations on that fly that you can find or imagine. e.g. Royal Coachman: Hairwing, fan wing, royal stimulator, coachman nymph, Coachman streamer, matuka coachman, para coachman, the list goes on.
4. Make a shadow box presentation as a gift.
5. Give all your tying tools and supplies to a school fly fishing club. Better yet, find a school fly fishing club and volunteer your time to help instruct novice fly tyers.
6. Learn to crochet.
