Your emotional stability is directly
tied to your awareness of other's needs.
Think of children, they're emotionally
volatile because they're completely self-absorbed. Their emotional state
is never adjusted to account for those around them.
Now see the other end of the spectrum,
Jesus endured the most self-deprecating experience possible because of the joy
that was set before Him (Heb 12:2). His joy was knowing the way to God would be
made available by His sacrifice. His emotional state was completely balanced by
His awareness of others.
Maturity is simply being aware of and
attending to the needs of others around you.
