What is attachment as per Buddhism? Is attachment some kind of love? Parental love, a smile that comes when we get a glance of a toddler, when we spent money on good for our beloved one's then that time what is it?

As per my perception i wish to ignore all of this, attachment. But i am actually unaware of the factual attachment. Am i wishing good? I am open for good, for change as i am aspired to become a good or maintain a fair balance between good and bad in myself to lead a good way of living. Literally i have came to know that i need a fair personal practical advise.
Teacher S.L. gave the following examples of attachments: attachment to basic pleasures, attachment to possessions, attachment to "good looks", attachment to comfort, attachment to stability of life, attachment to predictability, attachment to plans, attachment to knowing "exactly how" before you do anything, attachment to skills and abilities, attachment to being right, attachment to intellect, attachment to accumulating knowledge, attachment to the idea of success, attachment to what others think about you, attachment to committed relationships, attachment to fairness, attachment to high moral standards, attachment to spirituality, attachment to doing everything right, attachment to how it is "supposed to be", attachment to a theory, attachment to Dharma, attachment to Enlightenment.

Another teacher explained these as simply attaching way too much importance to ideas...

Teacher I.L. further explained these as preconceptions - overgeneralizations of our past experience that we identify with. We are so convinced that these are justified that we consider them part of who we are, of our values - which we assume to be absolutely correct because they are based on our limited experience.

Chogyam Trungpa Rinpoche further explained these as appropriating some familiar ground or territory, from which we then engage in dualistic relationship with the rest of the world. From his explanations, these attachments are the constituents of the ego. Feeding them is feeding the ego and therefore feeding Samsara.
