I get asked this question a lot, and it's a fair one.
HOW do you start strength training if you've never felt like you belong in the gym before?
HOW do you eat just a few bites of "bad" foods?
HOW do you wake up in the morning and not hate on your stomach?
HOW do you dance when you're a clumsy dancer, or write when you're an unclear writer, or love when you're an insecure lover?
There aren't always easy answers, and, "just start," while true, isn't very helpful in the swirling overwhelm.
