Happy/ happiness has advantage which is, When we're happy, our brains are more motivated, engaged, creative, energetic, resilient, and productive.
Thank you for sharing. I was not aware of this possibility. Actually, perhaps it's better to write that it's not a concept I have been witness to in my life. I never thought to associate happy with productive in terms of working towards something.
Determination, drive, and the unstoppable force that draws you closer to your goal is what is important. I guess I should write "was" important. I know you need to be happy, or content, with something to stick to it though. I'm not sure why I never put two and two together.
