They were at my place multiple times over a two week period before bringing out a robot.  

Think of them as robots, and you might be closer to the truth...

i have been doing this for about five months now recieving phonecalls from mymailing list. many people say to just let them talk and listen to what they have to say or find the solution to their problem.some of the poeple i talk to though are just very silent and do not talk much at all, and i feel like a robot when i am asking them questions. any suggestions on how im supposed to go about this?

Their zestimate is based on some robot comps.  

To let them know I am still treating each owner as if they are my only client I want to send out handwritten cards (some actually written by me and some via our robot service.)

Per Cathie Wood's ARKK Innovation strategies, these are the tech revolution area for next 10 years:Deep Learning ( Nvidia, Google,FB)Re-invention of data center (Cisco, Junipers)Virtual Worlds (Microsoft,Apple)Digital Wallets (Square, Paypal)Bitcoin (paypal/Visa)EV (Tsla/Nio/Xpeng/QuantumScape,Blink,Chargepoint)Automation (Apple, google, everybody)Autonomous Ride Hailing (Uber)Delivery Drones (Amazon)Orbital Aerospace (Nasa,Lockheed,Spacex)3D printing(HP)Long read sequeincing (Genentech)Medical Robotics (Intuitive Surgical)Cell and Gene Therapy ( many startups)All these companies has HQ and research facility in Bay Area.

They got those robots now. 

Do what you're comfortable and natural at and it will come to you with small adjustments, don't read some Ben Kinney scripts verbatim at an open house, and expect your robotic reactions to garner any real interest. 4) Network your butt off!

I work as an engineer in the semi-conductor industry currently and I'm considering going back to school for 4 years to finish my MS in Robotics to make my dreams of becoming a remote robotics engineer a reality.

I put my head down and I figured it out... mind you I am a former NASA robotics scientist, so I may have a slight advantage "figuring things out"... but I still firmly believe that anyone doing this on their own will far outperform any service providers or so called expert out there!
