While I believe in "Do one thing and do it well,"... I think it's good to stretch your skills. After the first of the year perhaps you can participate in some of the challenges.
I started leather work in Junior High. Did it for a couple years and then the death of my both my parents by the time I was 18 lead me down a path of self destruction for a while. I left leather alone for a long time, until about 6 years ago when I went half crazy and bought a bunch of tools and leather projects on Ebay. I "attempted" one small project and the others sat in a closet until about a year ago when my husband's belt broke and we had no money to buy him a new one. I dug out the belt blanks I had an did a simple border design. Then I re-did a wallet that the previous owner of the tools attempted. Then a checkbook case... and a dasher bag from the things I had. I was off an running. I found LW.net and have learned a lot.
Long story, shortened. I own several guitars. While in a chat with other guitarists.... someone asked me what I had been doing lately. I showed a picture of a practice piece and simply said. "I think I'm going to make myself a guitar strap." The next thing I new I had an order for a guitar strap. Eureka! lol I'm still doing guitar straps (and pick pouches) but still haven't made one for myself, yet. I think I am ready to branch out a little too.
So, I guess my advice is to look toward another hobby you may have your "focus" may lay in that field. For instance, an athlete might find a leather gym bag a good project. A bowler might want a leather bowling bag. An archery enthusiast, a quiver, etc.
