I volunteer at to give IT support at our local library. I do my best to work out how to help the person sitting next to me. I don't see anyone as being 'stupid' for not having a 'techno brain'. I'm not superior, I can't write poetry or draw anything recognisable (or abstract for that matter), I'm not 'well read'.
However, the world has moved on and many are disadvantaged because 'technology' is not for them.
If I can help, I will. Most customers say they are useless when it comes to technology. Understanding something new takes time and patience. My advice is to give yourself a break, ask for help from someone sympathetic and be willing to take your time with them to gain some understanding. In that way, both benefit.
I don't always succeed, but when a customer stands up at the end of a session and thanks me because I have been able to help them, I feel really pleased for both of us.
