Easy way to get VIGNETTE effect

I have a veeery old and simple version of Photoshop on my laptop, and have been trying to see how I can easily add vignette effect to pictures... I found a lot of the tutorials online to be very complicated.... At last I have come up with a way:

1. Open your picture in PS

2. Select a narrow border by using Marquee Tool:

 

3. Inverse selected area:

 

4. Select feather tool - choose 200 pixels:

 

5. Adjust brightness, to achieve a darker border:

6. Press CTRL + D to deselect

- and VOLIA! you have a beautiful vignette style border!
