Yet, in seeking assurances, they frequently receive cautions, which can easily be used as excuses for inaction.
Be aware that those who love you the most may be the loudest in warning you not to risk. Even when your mind and body signal perfectly good reasons for giving up, you go on.
This tough is obvious. But tough can be seen every day if we choose to look. Tough may be a patient undergoing cancer treatments or a single mother struggling to raise children. Tough can be an alcoholic ready to face rehab or an athlete living in a wheelchair.
Tough can be rejecting false praise and honestly accepting you and your children for who and what you are. Tough is an ability to make the best from what you are given. Tough is making the decision to replace self-pity, complaints and dependence with self-reliance, independence and action. Self-reliance and self- confidence will demand your toughness.
Then, you must temper toughness with kindness, realizing that many times it will be tough to be kind.
Be kind anyway. Since you seek growth, you must seek change. You must see yourself and your environment not only as it is, but also as it could and should be. You seek the changes necessary to reach the better you so that you can play your part in making a better world.
First, you change yourself. Can you change your day and spend more time with your family? Can you change your standard lunch routine and take a walk? Can you change your drive home and stop at a nursing home for twenty min- utes and see someone who may have few visitors? Can you change your office habits and find the time to make five more phone calls? What are the possible consequences of not changing? Doing little with your life is much easier and safer than taking risks, but then you will be a small person.
Instead, seek the changes which will allow you to be all that you can be. When your test is graded, to what will you attribute your success: study, hard work, personality, talent, skill, oppor- tunity, connections, patronage or luck? No amount of material success earned and kept will be awarded credit.
The greater your blessings, the greater your obligation to share your good fortune.
Use your special talents to serve the common good. Let your actions be moti- vated by a commitment to charity and justice.
Be compassionate, kind and con- siderate. Free yourself from your attachment to things.
The Action Principles are your ideals. Right now is the time to consider your blessings. Start scoring points. All humans from all countries and cultures are equal without regard to race, color, creed or gen- der. Believe with confidence and trust that the vast majority of people whom you meet, befriend or do business with are more similar than different from you.
People are inherently good. Most people act in good faith. They mean you no harm and would assist you in time of need. Do not become a party to rumor or gossip. Reject stereotypes and the divisive and demeaning policies that group people into categories. Be the first to build bridges of tolerance and understanding. It is an ideal. It is you at your best. Keep working.
You are calm, thoughtful, patient and confident. You are honest, trustworthy, responsible and reliable.
You are loyal and proud. You are humble and reverent. You are tough, self-reliant, persistent and hard working. You are organized, neat and poised. You are inquisitive and teachable.
Steady yourself with your arms? Thus, Euler made an equivalent and apparently independent statement of the variational principle in the same year as Maupertuis, albeit slightly later. That said, you can give your character a better chance of being appealing by making them attractive to look at. In practice, the success of your animation is going to depend on your sense of timing. Maupertuis' principle and Hamilton's principle exemplify the principle of stationary action. Luca Vitagliano. Alexey A.
You are healthy, vibrant and enthusiastic. You are kind, friendly, helpful and generous.
You are brave and daring. You are moral and ethical. You will feel a zest for life. You will live full, enriched days. This will happen because you will have taken the quiet time to think, organize and prioritize your days. You will love many things and these things will become part of your day. You will be in control. Every day you will do good things for your- self and others. Words like boring, bland and uneventful will rarely describe your work or your relationships. Listen to your favorite CD. Call a friend. Read a good book.
Take a walk and look at all the wonders of your world.
Let every- one in your life know that life is worth living. Be known as a motivator. Ask others about their goals and how you can help them. Make people feel part of a successful team. Solicit their input. Keep every- one informed and involved.
Establish performance incentives. Look for oppor- tunities to praise and reward.
