How right is this?

Hi DummyBlog! We are all here today in myLot partly because of the dedication and the teachings we have received from our teachers. Apart from our parents and families and the environment we live in as well as our own personal experiences, commitments and undertakings and for whatever reasons, we have all met here. Teaching, whether informally or formally is a very serious business. It is the early teachings in one's life that usually lay the foundation of and help shape or mould a person's reasoning, analytical, mathematical, language-arts and a lot of other interpersonal skills as well. A good foundation helps in developing a good skills required for life. This may be the essence of a long-lasting happy and fruitful future. Unless nothing changes, the opposite is also true. If one is good in technical know-how, teaching it would bring a lot of advantages, as I see it. However, the decision to teach or not depends on him/her. I would like to think that doctors and the medical professionals, on the other hand, are equally good as teachers and practitioners in their fields. Our parents remain as good teachers in life-skills. Teachers are people with substance, conviction, conscience and minds, not just to spend time with and they earn a salary. If I could rephrase the statement it should read: "Those who can, do and teach!"
