Knots usually take 1 minute or so to do. If you keep on tying the knots and get used to the pattern, you will get faster and faster and eventually will be able to do it in 4 seconds. It is kind of like picking strawberries. If you keep on picking strawberries and timing yourself, you will get faster like when you typed the knot
        
                    
             
        
        
        
Poem: A new way see life 
In the mist of the shadows
My pain become a sorrow
A time to make myself own
Was the one to be sown
I felt like you didn't wanted me
But I know that you granted me a gift
A new way, a new life 
A new hope
So, come be with me 
for here I am, waiting for you
