When others have problems, let them be, do not give advice or try to solve their problems for them. If they ask you for support, listen attentively, you will find this to be the most help you can give them. They know their problems best and usually will come up with a solution on their own.
Reading books can help and give you a deep theoretical background of things but, true understanding of life should start with an experienced teacher but, you must wholeheartedly take up the activity and practice it diligently to really understand things.
Begin a large task in its formative state because larger problems grow from small ones. You can accomplish great tasks with a series of small acts. Be aware of those who promise quick and easy solutions. Accept problems as challenges, do not dwell on them, take action.
What is called common good may not always serve well. Unity may be cohesion for society, but unity of what? Dedicated to what? Shared life should be held together by choices, not by decree. To be true to yourself do not give up too much and certainly not your center.
Quote: If the only prayer you say in your whole life is “Thank you,” that would suffice.
