Omo... This is why its always best to keep business and pleasure aside. When you charge for your services, you will know those who are really interested in your growth as an individual. Some are only there for freebies, you'll see that even if they had the money to pay, they'll go somewhere else.
That's just life for you.
Thank you for sharing this with us.
This is so true, it took me awhile to understand this but eventually I did.
Thanks for your enlightening comments, it is highly appreciated.
