Perfecting and delivering your tone is very important for making good first impressions.so here are a few things which will cerainly boost up your confidence.
           Keep your head held high, looking people in the eye at all times. Always hold your gaze a second longer if you happen to make eye contact.
          Never look down and away if someone addresses you or is the slightest bit intimidating. This is a sign of weakness. Pay attention to this, and eliminate this
negative habit.
          Lastly, your voice. Do you stutter in situations where there is the slightest bit of pressure? Or do you project a manly, confident tone delivered slowly and
smoothly. A weak voice is a certain sign of low self-esteem. Speak up and make yourself heard!
          When making a first impression, remember to smile. This helps your vibe become friendly, confident and approachable. People are more likely to want to talk
to you if they sense they will be received well
          With the combination of improving these small areas, you will be well on your way to succes.
