First of all: Congrats on making it home! I always get paranoid when I get back to civilized systems.
Take a break from exploring until it's lure pulls you back in like a Tony Soprano on steroids!
Then get an ASP Explorer (or an Anaconda, if you're into fat whales), fit it and become best buddies with Felicity Farseer.
Let her engineer your FSD and she can also help you make some other components lighter.
Enjoy your new Scarab garage.
Get an astronomy book or two, watch a few space documentaries on YT or Netflix. Say: "That's where I wanna go!"
And go!
You might also try to hijack/make a few friends to explore together or sign on to an expedition heading out.
So much to see in the galaxy after all... Just yesterday I found the most impossible systems and I wasn't even searching hard.
Lastly, don't be a stranger. It's always nice to meet another explorer somewhere deep out in the void!
