I'd definitely say that the biggest disadvantage when it comes to a "Paid" Mentorship is that the mentor can become relaxed due to them already being paid. So it's typical for people to not work as hard with status of "paid" as opposed to a mentor who has to work for their money, having the status of "unpaid." An paid mentorship (not definitely) can cause the mentor to not care about the importance of their job and how important it is to be sincere about mentoring you. It just depends on the integrity of the mentor one comes across. So I believe that the BIGGEST Disadvantage of a Paid Mentorship is a lack of sincerity, enthusiasm (energy), failure to manage time properly (yours and theirs) which is a la k of respect for you and your purpose of signing up to be mentored. So my advice would be to do your research on any and every mentor before attaching yourself to them and ultimately trusting them with your personal information and situations because it can lead to a waste of your time and a waste of your money.
