Rafael Gurkovsky, Life hacks (Productivity): Second Monitor
Now this might seem irrational, but a second monitor can actually make it easier for you to work. Employees notice that switching from one window to another actually makes it harder for them to concentrate on what they're doing. With a second monitor, however, it seems as though the whole process has just become way easier, no to mention easier on the eyes. Also, monitors today have become cheaper so this shouldn't dent your bank account too much.
A life devoted to things is a dead life, a stump; a God-shaped life is flourishing tree. [Proverbs 11:28]
— Rick Warren, The Purpose Driven Life: What on Earth Am I Here For? —
9 Two are better than one,
because they have a good return for their labor:
10 If either of them falls down,
one can help the other up.
But pity anyone who falls
and has no one to help them up.
11 Also, if two lie down together, they will keep warm.
But how can one keep warm alone?
12 Though one may be overpowered,
two can defend themselves.
A cord of three strands is not quickly broken.
