What's gd

My friend try to accept
What is true
That means 
The good and the 
Bad 
The 
Highs 
And the 
Lows 
Since these 
Help mould 
You
There are days 
You may feel 
Like the world 
Is against you 
There are other 
Days 
Were everything 
Seems to work 
Out for you
You see
As everything 
Has it's own 
Counterpart
You cannot
Have the good 
Without 
The bad 
Or be happy 
And 
Not feel sad 
But how 
You choose 
To move 
Forward 
That my friend 
Is a whole other 
Kind 
Of demand
