Connecting to the Matrix

Today I start to configure my VPS.
I connect to it via SSH with putty. I only will see white text on a black window, and I will type Linux commands and cofiguration settings all day. Soon, I will not be able to know which is the real world. So dangerous!
Whether, will I be able to connect out from there in the end of the day? Whether, will The VPS has me? Should I follow the white rabbit?

My one chance there is no Windows on my VPS.
