The third step
Tweak the monitor controls so that it matches prints as close as possible. You could use a printed test image for that but there is a way to get test images and sample prints at no cost.
SmugMug is in the business of selling photo prints using some of the major print labs like EZ Prints, Bay Photo, and WHCC. Prints not matching monitors is a frequent occurrence so they have a Sample Pack Request Form to request a Calibration Print and Sample Pack from these labs (US, Canada and UK only).
Here is the link to the request form: Sample Pack Request.
They will email you 7 digital photos and when you receive the sample prints mailed to you from the labs you can tweak your monitor to match the prints as close as possible. You will notice that brightness and color temperature require some adjustments.
Did not get an email back from them? Here are the sample test prints digital images:

If you want what you see on your monitor (IPS panel technology) to perfectly match your prints, the only way to go is with a calibration device which is much more efficient than our dear human eye.
Using a calibration device of some sort like the spider 5 pro is fast and easy.
