SAGITTARIUS (Nov. 22-Dec. 21): I don't recommend burning wood to heat your home. Such fires generate noxious emissions harmful to human health. But hypothetically speaking, if you had no other way to get warm, I prefer burning ash and beechwood rather than, say, pine and cedar. The former two trees yield far more heat than the latter two, so you need less of them. Let's apply this principle as we meditate on your quest for new metaphorical fuel, Sagittarius. In the coming months, you will be wise to search for resources that provide you with the most efficient and potent energy. CAPRICORN (Dec. 22-Jan. 19): The world's longest tunnel is more than 35 miles long. It's the Gotthard Base Tunnel in the Swiss Alps. I'm guessing the metaphorical tunnel you've been crawling your way through lately, Capricorn, may feel that extensive. But it's really not. And here's even better news: Your plodding travels will be finished sooner than you imagine. I expect that the light at the end of the tunnel will be visible any day now. Now here's the best news: Your slow journey through the semidarkness will ultimately yield rich benefits no later than your birthday. AQUARIUS (Jan. 20-Feb. 18): Would you like to avoid wilting and fading away in January, Aquarius? If so, I recommend that during the coming weeks, you give your best and brightest gifts and express your wildest and most beautiful truths. In the New Year, you will need some downtime to recharge and revitalize. But it will be a pleasantly relaxing interlude — not a wan, withered detour — if in the immediate future you unleash your unique genius in its full splendor. PISCES (Feb. 19-Mar. 20): My treasured Piscean adviser, Letisha, believes it's a shame so many of us try to motivate ourselves through abusive self-criticism. Are you guilty of that sin? I have done it myself on many occasions. Sadly, it rarely works as a motivational ploy. More often, it demoralizes and deflates. The good news, Pisces, is that you now have extra power and savvy to diminish your reliance on this ineffectual tactic. To launch the transformation, I hope you will engage in a focused campaign of inspiring yourself through self-praise and self-love. ARIES (Mar. 21-Apr. 19): If you were walking down the street and spied a coin lying on the sidewalk, would you bend down to pick it up?…
