Famous quotes containing the words positive and/or control:

    A positive learning climate in a school for young children is a composite of many things. It is an attitude that respects children. It is a place where children receive guidance and encouragement from the responsible adults around them. It is an environment where children can experiment and try out new ideas without fear of failure. It is an atmosphere that builds children’s self-confidence so they dare to take risks. It is an environment that nurtures a love of learning.
    Carol B. Hillman (20th century)

    Only one thing is certain: if pot is legalized, it won’t be for our benefit but for the authorities’. To have it legalized will also be to lose control of it.
    Germaine Greer (b. 1939)
