Whether something is self-evident depends on the context and the individual's perspective. Some concepts or truths may be considered self-evident to one person but not to another. In general, self-evident truths are those that are immediately obvious or universally accepted without the need for further explanation or justification. However, what is self-evident to one person may not be to another, so it is important to consider different viewpoints when determining if something is self-evident. **

While some concepts may seem self-evident to some individuals, it is important to remember that not everyone may share the same understanding or perspective. What may be obvious to one person may not be as clear to another, due to differences in knowledge, experiences, or beliefs. Therefore, it is always beneficial to communicate and explain ideas thoroughly to ensure mutual understanding and clarity. **

Set theory is considered self-evident because it provides a foundational framework for understanding the concept of collections and their properties. The basic axioms of set theory, such as the existence of the empty set and the concept of subsets, are intuitive and can be easily grasped. Additionally, set theory serves as the basis for many other branches of mathematics, providing a clear and consistent language for expressing mathematical ideas. Its self-evidence lies in its ability to capture the fundamental nature of collections and their relationships in a simple and intuitive way. **

On the wedding night, it is self-evident that two individuals are coming together to start a new chapter in their lives as a married couple. It is a night filled with excitement, anticipation, and love as they consummate their marriage. The commitment and bond they share become more tangible and real as they begin their journey as partners for life. **

It is unclear without more context who "he" refers to in this question. However, if we assume "he" refers to a specific individual, then whether something has become too self-evident for him would depend on the specific situation and the individual's level of understanding or familiarity with the subject. If something has become too self-evident for him, it may suggest that he has mastered the concept or topic to the point where it no longer presents a challenge or requires further exploration. **

One can develop self-confidence and resilience by setting realistic goals and working towards achieving them. Building a support system of friends, family, or mentors can also help in boosting self-confidence and providing encouragement during challenging times. Additionally, practicing self-care, such as exercise, meditation, and positive self-talk, can contribute to developing resilience and the ability to bounce back from setbacks. Lastly, learning from failures and viewing them as opportunities for growth rather than as obstacles can help in building both self-confidence and resilience. **

It should be self-evident to keep one's promise in situations where trust and integrity are crucial, such as in personal relationships, business agreements, and professional commitments. Keeping one's promise demonstrates reliability, honesty, and respect for others, which are essential for maintaining healthy and successful relationships. Failing to uphold promises in these contexts can lead to broken trust, damaged reputations, and negative consequences for all parties involved. **

You can get motivation and self-confidence by setting achievable goals for yourself and taking small steps towards reaching them. Surrounding yourself with positive and supportive people can also help boost your confidence and motivation. Additionally, practicing self-care, such as exercise, healthy eating, and getting enough sleep, can improve your overall well-being and confidence. Finally, celebrating your successes, no matter how small, can help build momentum and keep you motivated. **
