In order of importance to me for this year's firsts:
Took my granddaughter fishing and together we caught a crappie and a bluegill. (She held the pole and I helped her reel, she couldn't quiet turn the reel on her own, she's 2.)
Took my daughter fishing, she came a couple times last year, which was my first year fishing ever, but she never managed to hook anything, but this year she caught bass, crappie, and bluegill with me.
Went fishing with my wife multiple times.
Caught my first ever King (Chinook) Salmon wading in Lake Michigan.
Took up fly fishing.
Caught my first rainbow trout, which was my first catch ever on a fly rod.
Fished my first trout opener, caught my limit of delicious rainbow trout.
Explored many new bodies of water and caught fish at all of them.
Took up wading.
All in all, even though it was my only second year fishing, I can confidently say it will be hard to beat. I learned how to wade and fly fish. Caught hundreds and hundreds of fish. Last year, my first year fishing I literally caught bass only. This year I caught bluegills, perch, crappie, bass, catfish, trout, and salmon.
Wading with the fly rod is my preferred method. Bluegill are my favorite to relax and fish for. Salmon are my favorite sport fish, and perch are my favorite to catch to eat.
What a year.
