What we can change is our perceptions, which have the effect of changing everything.
Inspiration, Zen, Education
The effects you will have on your students are infinite and currently unknown; you will possibly shape the way they proceed in their careers, the way they will vote, the way they will behave as partners and spouses, the way they will raise their kids.
When you catch yourself slipping into a pool of negativity, notice how it derives from nothing other than resistance to the current situation.
Zen, Spirituality
When you blame, you open up a world of excuses, because as long as you're looking outside, you miss the opportunity to look inside, and you continue to suffer.
Courage is often associated with aggression, but instead should be seen as a willingness to act from the heart.
