Find some wild trout streams somewhere that are not completely frozen over. Preferably freestoners, as the trout there seem to be a bit more opportunistic when it comes to feeding. Pick a day when the temperature trend is upwards (but not too high, or you'll be dealing with depressed water temperatures because of snow melt), cast, and enjoy catching. I know you didn't catch anything yesterday, but the day fit the description I outlined and I had some success with a black size 8 bugger (so much for the go smaller mantra I usually follow in colder months).
But, as others have noted, don't burn yourself out on winter fishing. If you aren't having success catching, better to stay at home, read up, tie some flies and tackle the water when it is warmer. However, consider that a wild trout freestoner this time of year will provide some phenomenal scenery and ice sculptures, which in and of itself is worth the walk. The fish are just bonus, so enjoy the hike by itself. This is also the time of year when the water can be low and gin clear, devoid of most of the sediment that seems to appear during the summer farming months, so it is also an opportunity to get a really good observation of what particular holes on a stream look like.
