What are some useful skills I can learn in a few minutes?

This is just a little advice:

Look at this man...

Seems to be good..??

I suppose not.

Now look at this man...

Seems to be good..??

For sure..!!

A small improvement in posture can make a big difference in your personality. Just keep your back straight while talking to someone. (Especially your boss or any colleague)

Make a good impression and you will definitely feel a wave of confidence passing through you.

I'm also trying to adopt this in my daily life.
