Yeahhh!This is so true! Sometimes you affraid to show who you are.
Sometimes parents push you too hard to be someone that they've been dreaming about.
Sometimes they really know what you need for your future.
I don't want to say that you must against your parents but showing people the truly you is the best to get success.
Do what you like or what you love.
When you do something that you like or love, you will do it with your heart.
And the result will be amazing.
The important things: Never show your emotion when you tell that to them. Showing to them that you already grow up now, talk wisely and give them the simple way to undertanding what you want to do with your life.
You only live once, so use it just like you want.
My advise: Just try anything that you want!
Maybe oneday you will find your soulmate job that you love so much :)
