Have kids and getting married doesn’t make you any more mature or your life fulfilling than not having them. Anyone can have kids as long as they are biologically able to. The question is are you willing to sacrifice your life to raise them and provide for them? It’s a life-long responsibility that has no return policy!

As for your investments, you should put that 100k from least to most conservative either in an S&P 500, target date fund, or HYSA. You’re literally losing money by just keeping it in the bank cause of inflation.

To make it easy, start off with plugging your old laptop into external monitor. Install RDP, VNC, ssh, ftp depending on your OS. Install tailscale and join the network. Now with another computer, connect to that same network with tailscale and then you can connect and see your laptop screen with RDP. Or if you want VNC you can get a “dummy” hdmi adapter or try installing software for dummy monitor output. After that, use wired ethernet to plug old laptop in router, set to never turn off (recommend removing laptop battery beforehand) and there you go, you have your own personal server you can access anywhere including your phone! From there, look into self-hosting with apps like jellyfin, immich, etc. tons of great resources online.
