Well looking back now to 1976 when I got into the trade,I had the option of that or working for a telephone company. Should have went with the phone company...geezz we even have to run pipe for them to come along with 8 guys to pull in the wire. The trade has totally wrecked my back and have been out of it since 1989.
Depending on your age you will have to consider this is not just putting in light switchs and light bulbs...thier is alot of heavy manual labour involed, my fist job was a 12 story apartment...guess who was running the bundles of pipe up the stairs to the top floors...yep ME.
