Many people are hospitalized everyday because they get their fingers jammed in their mouse using poor clicking technique. I am here to teach you a fool proof technique that avoids injuries, is simple, and maximizes clicking efficiency.
You'll be clicking like the best.

First thing I want you to do is to reach for your mouse with your dominant arm.
Place the Palm of your hand on top like your cupping a potato. Make sure your Index and Pointer fingers are positioned on the Left and Right Triggers.

Note: Right Clicking is a fairly advanced technique and is out of the scope of this guide.

Maneuverer the mouse to where you wish to click and apply firm pressure to the Left Trigger using your Index finger. Release the pressure once your click is complete. Making Sure to rest your Index finger above the left trigger once more.

Congratulations, you have successfully Left Clicked.
