Take profits or keep riding the wave

Hey I'm up a lot on RKLB, LUNR and even on ASTS. That's 50% of my portfolio currently because it has grown so much.

I need someone that is not me to give me a reality check because reading another post on the front page made me realize I'm spoiled and greedy.

When is it smart to sell? There are news for RKLB for example launching a new promising rocket which would be great for the company.

Do I keep holding until there are no good news ahead? Do I hold until it starts going down like -10% and draw the line there to not risk momentum going up soon, because I could take a 10% loss.

Any suggestions, I'm open to new perspectives and ideas. Also considered just putting the money into 2x S&P100 because I don't mind taking a bit risk, I'm still young and working part time, no rent to pay because studying and living at my parents.
