When you're new to photography, one of the first things you learn is how to focus your camera on your subject. It's a no-brainer but it is the most important factor in getting good photos.
Similarly, in life, you got to have a focus point.
Whether it's your career or love life, a solid focus is required to tune out all the distractions.
It's when you focus on a particular idea to work on, all the other distractions go out of the window and you get to work on making your dreams come true.
In case of a person, when you start loving someone, they automatically become your point of focus. Everyone else just tunes out of your viewfinder and all you see is that one person amidst a crowd of hundreds. And that's what keeps your love life strong.
It's not something you acquire in a moment. It becomes sharper with time.
So, have you found your focus point yet?
