Well fish is good for you and it adds variety to your diet/cooking so you're not constantly just making chicken and shit.
Fresh fish doesn't stink and it's delicious paired with various vegetables. Give it another go.
Reading more into the benefits of fish, I see that the vital nutrient is omega-3; will look into fish oil until I can get in the habit of eating omega-3 substitutions such as mushrooms and nuts. Last time I had fish was in a seafood only restaurant a few months ago where it was heavily seared with lemon to neutralize that abominable odor.
