Do It Myself

I have had to tackle a lot of things myself in the house because my husband is gone a lot of the time. I understand that some things I must contract out, but I will always try to see how far I can get on my own first. I have decided to update our lighting in the house and before I call out an electrician I want to see if I can do it myself. I have purchased the cable lighting kit and I am going to undertake the project this weekend. How hard will it honestly be to install the lighting myself?
