+1 for taking as many photos as possible. I actually think physical photos are way better for memories and less risky long term. Hard drives fail all the time.

I would recommend getting a 35mm film camera and taking a LOT of pictures. Capture yourself, family, events, travel, life milestones.

You will only REGRET the ones you did not take.

Alternatively, something I am looking into, is printing a few hundred photos you have on your smartphone at the end of each year. Get the best ones in physical form to keep safe.
