Who are 'they'?

If you stop listening to your heart just because they say it wrong,

If you bound yourself because of their restrictions,

If you feel hesitant to express yourself in order of what they will think,

And if you kill your opinion just to go hand in hand with their thoughts 

My question is, who are 'they'?

Who are 'they' to stop you?

To roll you in limited line? 

And to restrict you from your possibilities? 

Simply, they are nothing but the hurdles!

Those hurdles which you yourself have to kick out from your life in order to hail success!
