By a staff reporter: To find long-term happiness, you need to retrain your brain from a negative mindset to a positive mindset. Try these things: Spendone to two minutes looking for positives in your life. Do this three times a day for 45 days, and your brain will start doing it automatically.Choose a positive mantra for the day -- something you will repeat to yourself, such as “Today is beautiful” or “I feel grateful for all I have.” And when things go south, take a moment to try and see it from a positive light. Never underestimate the importance of recognizing the silver linings in life.
