Advice on leap option

Hey all, I opened one leap for spy $600 strike Jan 27 for 102.46 and currently up 56% considering selling it and taking the gain as I can always open up another in the future. I opened the position to start a pmcc selling calls agianst the position. Question is do I hold it as the marlet can continue increasing? Or sell to secure gains? If spy did pullback 10-20% I would feel guilty that I didn't sell sooner. My theory for opening the position is to sell calls agianst it and use it as income for funding other stocks/ETFs. The strategy has worked so far very well on the market and I can forsee us continue riding higher Thinking about this I can see some options: Sell take the gain Close the current and use that money to open another Continue holding
