A little sincerity is a dangerous thing, and a great deal of it is absolutely fatal. - Wilde

If you don't like something, change it. If you can't change it, change your attitude. Don't complain.
Everyone has his inherent ability which is easily concealed by habits, blurred by time, and eroded by laziness.
Nuptial love makes mankind; friendly love perfects it; but wanton love corrupts and debases it.— Bacon
