2 . Have you ever been in a bathroom, dressing room or another private area with a mirror and had that feeling that someone is watching you? You can check to see if a mirror is transparent by observing how it is installed and using a few simple techniques to determine if there’s a wall behind it.     1    

Check out the lighting. For a two-way mirror to be effective, the light on the mirrored side needs to be 10 times brighter than the light on the other side. If the lighting is dimmer, it’s possible to see through the glass to the observation area. Look around and determine whether the lighting seems extraordinarily bright.     2    

    3    Press your face up to the mirror and cup your hands around it, creating a dark tunnel to block out as much light as possible. When you do this, if the light in the observation room is at all brighter than the light on your side of the mirror, you should be able to see something through the glass.

Sound it out. The sound of tapping a two-way mirror has also been described as bright or sharp as opposed to a thud (砰的一声) from an everyday mirror. Tap on the surface of the mirror with your knuckle (指节).     4    An observation mirror will produce an open, hollow and echoing sound because there is an open space on the other side.

    5    Then hold a flashlight to the mirror (it can be the “flashlight” on your smartphone). If it is a two-way mirror, the room on the other side will be illuminated and you’ll be able to see it.

4 . The early bird catches the worm, right?

There was a time in my life when it seemed I couldn’t advance at work. I had this coworker who was always one step ahead of me.     1     But for some reason, my normally strict boss seemed to love him.

Then one morning I headed into work half an hour early so I could also leave early to catch my flight for a weekend vacation. When I got there, my coworker and boss were chatting over coffee. I joined in and realized they had been having these morning chats for months!

    2     By missing out on these small morning coffee chats, I was missing out on building an important connection for my career. So it’s important that we look at how the time that we arrive at our events is affecting our lives.

Often, we rank things based on how we understand the importance of our punctuality for that event. How early would you show up to something like a doctor’s appointment? Do you get there right on time, or 15 or more minutes earlier?

Think about your job. If it’s more casual and relaxed, do you always show up on time?     3     Did you ever find yourself getting in trouble at work for being late?

Now think about personal events. If you went to a friend’s birthday party or their dinner, would you show up on time? Consider how you show up for even more casual hangouts, like, checking in with your parents.

    4    

When we show up early, we give ourselves the chance to reduce stress about missing out or making anybody else upset.     5
