Don't feel pressured; if you're under pressure, you will definitely lose. You won't be able to make the big profits you should, and you'll incur significant losses from mistakes. Here are a few suggestions: 1. Only trade mainstream and well-established options, 2. Don't take on too large a position, 3. Don't doubt yourself because of a margin call; if you make a wrong trade, just set a stop loss decisively once the price breaks.
