One of the most important and common pieces of advice constantly given on TRP is LIFT.

Now as a newbie, I have no clue where to start. I'm scared shitless of embarrassing myself at the gym and I'm also skinny as all hell (120 pounds, ~5 and a half feet tall).

Where do I start? How do I go about knowing proper form, how to make gains the right way, and also what to eat to get the best results possible? I really want to make these gains and improvements on my life but I legitimately have no idea where to start.
