Mentorship and have a mentor plays a vital role in the life. One can have spiritual mentor, financial mentor, educational mentor, business mentor and so on and do forth.
The question now is, how many mentors can one possibly have?
As many as possible, but a balance of both. Someone who is already successful and knowledgeable in the field you want to be in, and someone who has had many experiences in life that can teach you life values and help mold your mindset for personal development.
