Sometimes the presence of certain people in life can make everything better. Your mood, your days, nights, even your luck.
Every negative outlook turns into a positive one. Gloomy rainy day sky looks blue even when there's gray clouds gathered. Perhaps, the blue was always there but it took the right people to point it out to me. And it's not like you have to meet them everyday to have a good day, just knowing they are there, breathing in life beautifully will be everything. They encourage you to live everyday with a smile or they turn your life into a big happy smile.
When you find such people, don't let them go.
