Philosophy? Why?

It is a commonly accepted fact that Philosophy as a concept and and as accupation pulls its birth since the moment that there is human history,that is the "protoleia"--> first written forms of human memory.
 Listening to the term Philosophy,perhaps in our mind come some questions worth mentioning in order to reach it in the best possible way:
  ~ What is Philosophy?
 ~ Is it worth someone engaging with it?
 ~ Is it only theories or  is the springboard-epivasi-motive for  similar-analogical-corresponding projects and actions?
 ~ In which areas of human activity can Philosophy be  immediately and practically active,(i.e.in which areas and situations in life can we make use of it?)
 ~ When can we safely say that one is "allowed" to deal with the study and application of Philosophy?
 ~ What is the philosopher(i.e.what kind of person is/should be):
  {a} a rigorous unity / undeniable authenticity?
 {b} a continuous-never ending  learner?
 {c} a spiritual dispenser and simultaneously powered,that is a "feeder and an eater" of a spiritual feedback?
 ~ Should / must have a Philosophy practitioner high aesthetic criteria and superior moral values?
 ~ Should Philosophy both as a value and as a practical matter   be the last helter in difficult times/ dead ends or an "oiakas"--> steering wheel for the ship called  conscious life?

Philosophy is a safe steering wheel for the ship called  conscious life
