Good morning, everyone. First, I’d like to ask you a question. Are you happy?
    Life is a constant struggle. We look for happiness without knowing what actually makes us happy. We are busy doing things that distract us from the truth, though it doesn’t change the situation. Stop hiding. Look in the mirror and ask yourself, "Are you truly happy?" If your answer is "no, " then you probably need to change something in your lifestyle. Even the smallest thing can make a huge difference in how you feel. Who knows, maybe that little change will make you the happiest person in the world. You never know until you try. Choose one of these little changes that will make you happier, and make sure you make that change as soon as possible.
    If you are one of those who earn a lot but don’t know what to do with those bucks, give others. I know what you’re thinking, " I work hard each day and now I should give my money away. " Yup, you should if you want to feel happier. Believe it or not, giving makes us feel happy. Try once and you won’t stop. Besides, you don’t give money for entertainment. You help someone in need. If you don’t have money, offer your help without waiting for anything in return.
    Now that the fall season is here, why not connect with nature? Regardless of how successful you are, your soul strives to be closer to nature. A 20-minute walk in the park or a day spent near the forest, mountain or ocean is a simple way to become closer to nature. You’ll feel that invisible power that nature has and you’ll start feeling much happier, truly happier. Money provides temporary happiness, while nature brings happiness into your life for good.
    Get rid of the habit of saying negative things about yourself and people around you. This way, you spread negativity that affects people’s lives. Say nothing negative today, tomorrow, for a week, for a month and see how happy you and people around you will become. Spread positivity and happiness will find you itself.
    You have everything you want in life but all those opinions, rumors and gossips prevent you from being truly happy. Just stop caring about what others say and do, even if others are people you love. No matter what you do, there are people who will always rate you, dislike you, and try to break you. Stay strong. Listen to yourself, not to their opinions. It’s your life. Do what your heart tells you to do. Hope you enjoy today’s lecture. Thank you!
