If you are happy, you are more willing to forgive.. Yes Or No?

I was asked if I were happy more often, would it be easier for me to forgive people whom I've been upset or hurt by.

Yet, I've been taught that one shouldn't place their focus on happiness, which is transient and circumstantial. Instead, joy is to be the foundation of my life as it's based on the unwavering truth of God's promises and it's timeless and never changing in this fast pace society.

Cos what will last forever are the souls of Men and the Word of God.

However, the struggle with instant gratification, wanting to be happy always and feeling good is real. The memory of the God's promises usually fades away when I'm upset.

I would like to hear what are your thoughts and struggles on this..

How would you have handle this.
