There are different kinds of spices. Some are tangy, some are spicy, some are bitter, some are sweet, some are tangy.
Life is just like a mixture of spices.
Sometimes you experience good moments and sometimes you experience bad moments. Sometimes you're excited, sometimes you're depressed.
But that's how life is. Without all these different moments life is meaningless.
Without experiencing grief you can't know what happiness is. All things are related to each other.
Just like spices. Without tasting bitter things you can't know how sweet tastes.
So face everything happily because you'll definitely learn something from them.
