Life is difficult.
This is a great truth, one of the greatest truths. It is a great truth because once we truly see this truth we transcend it.Once we truly know that life is difficult —once we truly understand and accept it — then life is no longer difficult. Because once it is accepted, the fact that life is difficult no longer matters.
  Most people do not fully see this truth that life is difficult.nstead they moan more or less incessantly, noisily or subtly, about the enormity of their problems, their burdens, and their difficulties as if life were generally easy, as if life should be easy  They voice their belief, noisily or subtly, that their
difficulties represent a unique kind of affliction that should not
be and that has somehow been especially visited upon them, or else
upon their families, their tribe, their class, their nation, their
race, or even their species, and not upon others. I know about this moaning because I have done
my share.
Life is a series of problems. Do we want to
moan about them or solve them? Do we want to teach our children to
solve them?
Discipline is the basic set of tools we require to solve life's
problems. Without discipline we can solve nothing. With only some discipline
we can solve only some problems. With total discipline we can solve
all problems.
What makes life difficult is that the process of confronting
and solving problems is a painful one. Problems, depending upon their
nature, evoke in us frustration of grief, sadness, loneliness,
guilt, regret, anger, fear, anxiety, anguish, or despair.These are
uncomfortable feelings, often very uncomfortable, often as painful
as any kind of physical pain, sometimes equaling the very worst
kind of physical painIndeed, it is because of
the pain that events or conflicts engender in us all that we can
call them problems.And since life poses an endless series
of problems, life is always difficult and is full of pain as well
as joy  Yet it is in this whole process of meeting and solving problems that life has its meaning. Problems are the cutting edge that
distinguishes between success and failure.It is only
because of problems that we grow mentally and spiritually. When we
desire to encourage the growth of the human spirit, we challenge
and encourage the human capacity to solve problems, just as in
school we deliberately set problems for our children to solve.It is through the pain of
confronting and resolving that we learn. As Benjamin Franklin said,
"Those things that hurt, instruct."It is for this reason that wise
people learn not to dread but actually to welcome problems and actually to welcome the pain of problems.

人生是艰难的。这是一个重大的真理，也是最伟大的真理之一。它之所以是一个伟大的真理，是因为一旦我们真正看到了这个真理，我们便超越了它。一旦我们真正知道生活是困难的——一旦我们真正理解并接受了这个事实——那么生活就不再困难了。因为一旦被接受，生活的困难不再重要。
大多数人并没有完全看到这个真理，即生活是艰难的。相反，他们时而大声嘟囔，时而暗示地抱怨自己的问题、负担和困难之重，仿佛生活总是容易的，仿佛生活应该是易如反掌的。他们发出自己的信仰，大声或微妙地表示他们的困难代表了一种独特的折磨，不应该存在，而且在某种程度上特别地影响了他们，或者他们的家庭、部落、阶级、民族、种族甚至物种，而没有影响其他人。我知道这种抱怨，因为我也曾经这样做过。
人生是一连串的问题。我们是要抱怨还是解决它们？我们要教导孩子们解决它们的方法吗？纪律是解决人生问题所需的基本工具。没有纪律我们什么都解决不了。只有有些许的纪律，我们只能解决一些问题。只有全套的纪律，我们才能解决所有的问题。
使人生变得困难的是，处理和解决问题的过程是一个痛苦的过程。问题，根据它们的性质，会引发我们的挫败、悲伤、孤独、愧疚、后悔、愤怒、恐惧、焦虑、痛苦或绝望等不舒服的感觉，有时非常不舒服，有时甚至和任何一种身体上的疼痛一样痛苦，有时甚至等同于最严重的身体疼痛。确实，正是因为事件或冲突在我们身上引发疼痛，我们才能称它们为问题。由于生活提出了一个无尽的问题系列，生活总是艰难的，同时充满着痛苦和快乐。然而，正是在处理和解决问题的整个过程中，生活才有了它的意义。问题是区分成功和失败的关键所在。正是由于问题，我们在精神和心灵上都能得到成长。当我们希望鼓励人类精神的成长时，我们就会挑战和鼓励人类解决问题的能力，就像在学校里我们有意为孩子们设定问题一样。正是通过解决问题的痛苦，我们才会学到更多。正如本杰明·富兰克林所说：“那些让我们受伤的事物，也将给我们带来教训。”这就是明智的人不惧怕问题，甚至欢迎问题和问题痛苦的原因。
