Including intervals
Those are life stages
Go up and down
Gain and lose
That’s life rules
Positive and negative
Optimistic and pessimistic
Humans’ different thoughts
Of vicissitude moments in life
3sin x triples range sin x
Once you put in more effort
You can earn more
Once you dare to take risks
You’re ready to lose more
Bold or blurry
Weak or strong
Sine graph shows our heart beats
Burning with passion
Love and sympathize
Caring and understanding
Sine graph is life wave
Keeps raising and moving
Never can obstruct dreams and hope
Chasing desires of future
Life is a sine graph
