Open the image you want to use:
First, duplicate your layer.
Next, you will want to cut out the main object. I used the magnetic lasso tool for the guy in my picture. You can use whichever tool is easiest for you.
Once you have the whole image press Control J to put it on a separate layer.
If you want, you can temporaily hide the other layers so you can just see your main image and fix anything you need to.
(I had to erase a little part of the background that I missed with the lasso tool)
Now we will add the effects. Right click your new layer and go to Blending Options.
First we will add a stroke. Here were my settings:
You should have something similar to this:
Now and outerglow. And again, here are my settings:
The only thing you probably cant tell is I slightly changed the color. I kept it a yellowish-whtie just like the default, I just picked a little bit of a whiter color. I wanted to leave some of the yellow tint.
Now here is what mine looks like:

Next I clicked in my background layer, went to Filter > Blur > Gaussian Blur:
Your Blur number might be different, depends on the picture of course.
After that, I decided the background needed some color too. Once again, I went to Image > Adjustments > Hue/Saturation: (Again, just the saturation number)
And thats it!
You could also desaturate the background for a different look:
