Seeking most efficient options trainer

Motivated investor seeks options knowledge.
8 years experience in the stock market. Success with long term holds, momentum trading, swing trades, inverse and leveraged funds.
I’m seeking advice. Your formula that really helped trading options click for you. And helped you make your first trades.
I’ve read the books.
I’ve watched the YouTube series.
I’m yet to make a trade and a bit scared.

Is there an app that helps paper trade?
Is there a platform that trades options easier than another?
Who did you turn to when you didn’t even know the terminology well enough to know how and when to close out your positions?
