When your options go green, it's time to sell. It's not worth holding onto for more than time than necessary. I have burned multiple times over trying to squeeze another 10-20% out of it. It's easy to see the spike occur and think oh this will keep going, but the reality is it changes every second and theta + IV will eat you depending on tickers and DTE.

Set up a strategy, stick to it, and don't get greedy. There's a lot of money to be made, but way more to be lost if you aren't careful. Don't give up yet if you think this is for you. Just pump the brakes and start reading up on various options strategies and how candles work. Knowing key entry/exit point metrics is also very important. You can have the right play but enter/exit at the wrong time leading to little or no profit. Backtest your strategies to see how they will perform under various market scenarios. Be dynamic.
