Practice (learning method) in the context of "Knowledge economy"

A person's life stance, or lifestance, is their relation with what they accept as being of ultimate importance. It involves presuppositions and commitment to exercise it in theory and practice in one's life.

It can connote an integrated perspective on reality as a whole and how to assign valuations, thus being a concept similar or equivalent to that of a worldview; with the latter word (derived from the German Weltanschauung) being generally a more common and comprehensive term. Like the term worldview, the term life stance is a shared label encompassing both religious perspectives (for instance: "a Buddhist life stance" or "a Christian life stance" or "a Pagan life stance"), as well as non-religious spiritual or philosophical alternatives (for instance: "a humanist life stance" or "a personist life stance" or "a Deep Ecology life stance"), without discrimination in favour of any.

An expert is somebody who has a broad and deep understanding and competence in terms of knowledge, skill and experience through practice and education in a particular field or area of study. Informally, an expert is someone widely recognized as a reliable source of technique or skill whose faculty for judging or deciding rightly, justly, or wisely is accorded authority and status by peers or the public in a specific well-distinguished domain. An expert, more generally, is a person with extensive knowledge or ability based on research, experience, or occupation and in a particular area of study. Experts are called in for advice on their respective subject, but they do not always agree on the particulars of a field of study. An expert can be believed, by virtue of credentials, training, education, profession, publication or experience, to have special knowledge of a subject beyond that of the average person, sufficient that others may officially (and legally) rely upon the individual's opinion on that topic. Historically, an expert was referred to as a sage. The individual was usually a profound thinker distinguished for wisdom and sound judgment.

In specific fields, the definition of expert is well established by consensus and therefore it is not always necessary for individuals to have a professional or academic qualification for them to be accepted as an expert. In this respect, a shepherd with fifty years of experience tending flocks would be widely recognized as having complete expertise in the use and training of sheep dogs and the care of sheep.

Grooming (also called preening) is the practice of cleaning and maintaining parts of the body. It is a species-typical behavior.

A rehearsal is an activity in the performing arts that occurs as preparation for a performance in music, theatre, dance and related arts, such as opera, musical theatre and film production. It is undertaken as a form of practising, to ensure that all details of the subsequent performance are adequately prepared and coordinated. The term rehearsal typically refers to ensemble activities undertaken by a group of people. For example, when a musician is preparing a piano concerto in their music studio, this is called practising, but when they practice it with an orchestra, this is called a rehearsal. The music rehearsal takes place in a music rehearsal space.

A rehearsal may involve as few as two people, as with a small play for two actors, an art song by a singer and pianist or a folk duo of a singer and guitarist. On the other end of the spectrum, a rehearsal can be held for a very large orchestra with over 100 performers and a choir. A rehearsal can involve only performers of one type, as in an a cappella choir show, in which a group of singers perform without instrumental accompaniment or a play involving only theatre actors; it can involve performers of different instruments, as with an orchestra, rock band or jazz "big band"; vocal and instrumental performers, as with opera and choral works accompanied by orchestra; or a mix of actors, vocalists, instrumentalists and dancers, as with musical theatre.

Autodidacticism (also autodidactism) or self-education (also self-learning, self-study and self-teaching) is the practice of education without the guidance of teachers. Autodidacts are self-taught people who learn a subject through self-study. Process may involve, complement, or be an alternative to formal education. Formal education itself may have a hidden curriculum that requires self-study for the uninitiated.

Generally, autodidacts are individuals who choose the subject they will study, their studying material, and the studying rhythm and time. Autodidacts may or may not have formal education, and their study may be either a complement or an alternative to formal education. Many notable contributions have been made by autodidacts.
