Keep Fresh Flowers from Dying:
The simple answer is, surprisingly, vodka. The booze not only helps kill bacteria but helps replenish the nutrients lost from being cut off at the roots.

Adding a teaspoon of vodka to your plant water actually helps with the plant’s overall health of your flowers.  People may find this surprising, but the vodka acts as an antibacterial agent, meaning that it kills bacteria on the stems and promotes growth and a healthy plant overall. Once you add the vodka, make sure you remove any lower leaves that could leak bacteria into the water as they wilt.  Also, consider where to display your flowers; while they might look beautiful next to a sunny window, it is not the best place for them to thrive.

Smelling Roses Increases Calm:
You’ve always heard that it’s powerfully positive to "stop and smell the roses." Now science proves how right that is! Pause to take a whiff of these fragrant beauties, and you’ll feel soothing relaxation sweep over you within 60 seconds, according to research out of Japan. Aromatic compounds (citronellol and geraniol) that give roses their distinctive scent increase activity in the parasympathetic nervous system, which is responsible for helping your body and mind truly relax.

Going Barefoot Boosts Your Mood:
Becoming instantly happier is as easy as kicking off your sandals and walking barefoot in the grass. Feeling a soft, fuzzy texture against your skin triggers pleasant emotions as soon as you touch it, according to research published in the journal Consciousness and Cognition. That’s because over time, the brain becomes trained to associate touching soft surfaces like tender grass, a squishy pillow, or fluffy animal with enjoyable experiences. And every time you feel a similar texture, it automatically produces a happy feeling.

Make Your Own Window Cleaner: 
Put 2 cups of water, half a cup distilled vinegar and 10 drops of any essential oil (lemon, orange or grapefruit oil smells nice) in a spray bottle and shake before spraying.
