B is for:

BALANCE 

Balance as a goal in nature is important if ecological destruction is to be avoided and balance in lifestyle is an important goal if you want to avoid using too much time living in extremes which are frequently hazardous to your health and prosperity.

BEAUTY

Beauty as a goal is overvalued in this society where brains and good health should be valued even more greatly.  Breeding mostly for beauty in dogs and cats has led to breeds which are not very smart and have genetic flaws which cause poor health.

BELIEF

Almost everyone usually believes in something and it is important that most of your beliefs are based on objective facts and not subjective unproven opinions.  To believe that a goal is achievable is frequently the first step in its achievement.

BRAVERY

Bravery is trying to reach a goal(s) under very dangerous circumstances.
