Try not to start with 'I want a career,' but with 'what area do I want to improve in?' Consider the situations in which a philosophical education could be useful. Try to acquire a place in the most entry-level position possible, such as an intern, where no prior work experience is necessary. The pay is low, but you will get experience and seniority. Then you'll seek another position, taking your experience and high pay into account. However, if you acquire a position in a major corporation, you will have opportunities for advancement. You may earn a second education while working on your profile.
It is normal that until you have confidence, it will come with experience, as you have seen in movies.
