Sound waves are a type of power

We are surrounded by sound waves. Sound has the power to communicate ideas, scare us, entertain us, even help us fall in love.

Sound waves are a kind of energy that is launched when an object vibrates. These waves travel through a medium like air or water. When they reach your eardrum, the brain translates the pressure waves into words or music.

Wellington - the capital city of New Zealand

The bayside city has a population of about 200,000 people. It has red cable cars and its Old Government Building - constructed in 1876 - is still one of the world's largest wooden structures. Wellington is known as one of the easiest places in the world to start a business.

Hip Hop Education

In The US, there is a growing movement towards Hip Hop education, with the music style which is generally associated with breakdance and graffiti being used for self-expression, better social life, fitness and professional development.

Hip hop music has mostly been a patchwork of sample tracks from other songs, and the same philosophy has been a part of various schools and universities in the US, where it is encouraged to pick and choose ideas from other places rather than sticking to a rigid formula.

Stop Taking Things Personally
  • When people criticize you or reject you, it has way more to do with them,(their values, their priorities, their life situation) than it does with you.
  • When something you do fails, it doesn’t mean you are a failure as a person; you are a person who happens to fail sometimes.
  • When something tragic happens and you suffer, remember that hardship is part of choosing to live.

Experiencing social anxiety on social media

Social media has many good qualities but is also fraught with challenges for people who are socially anxious. They may feel as self-conscious as they would face to face. They may think that they don't have anything to say, that they come across as boring, or that people may think they're stupid.

These fears affect how people behave, causing them to hold back and hide their true selves. In turn, it makes them feel even more boring or quiet, making them share even less about themselves.
