Life is a series of lines: vertical, horizontal, zigzagging... always with a direction.
Life is a line. It has its ups and downs, but ultimately, it's how you live it that counts.
There's a fine line between genius and insanity.
There's a thin line between love and hate.
The line dividing good and evil cuts through the heart of every human being.

The shortest distance between two points is a straight line, but it's often the curviest and most challenging.
A line is a dot that went for a walk.
The line between adventure and stupidity is often blurred.
Every line is the beginning of a story.
The only lines that matter are the finish lines.
Some lines are worth crossing if it means you'll find yourself on the other side.
Cross the lines that limit you.
Life is like a line. The straighter it is, the smoother it flows.

Drawing a line in the sand is easy. The real challenge is not crossing it yourself.
Draw the line somewhere.
Straighten your lines and you'll straighten your life.

There is no line between art and life; the line is art itself.
The line between failure and success is so fine that we are often on the line and do not know it.

Every line is the path of a moving point.
