The quote "Focus on being happy and positive things will come into your life" is often attributed to several different authors or sources, and it is considered to be a general motivational or self-help saying rather than a specific quote from a particular individual.
These types of inspirational phrases are often shared on social media, in self-help books, and by motivational speakers. They encourage individuals to maintain a positive outlook, as it can potentially lead to a more fulfilling and positive life. However, it's important to remember that while positivity and a happy mindset can be beneficial, life's circumstances are multifaceted, and external factors beyond one's control can also play a significant role in shaping experiences.
