Bath/Pamper products question - Where to start with it all?

Over the past couple of years, I have received pamper packs from people close to me, but have not yet gotten around to using any of them. By pamper packs, I'm referring to gift packs containing some or all (or more than!) the following:

Moisturiser/body lotion/body butter

Shower gel

Bath salts

Hand creams

Makeup

Serums, lotions, hair product......... the list goes on!

Here's what's funny. Compared to most girls, I'm kinda scarce when it comes to using this sort of stuff (which is probably why they get it for me in the first place!) and usually when I buy something like a moisturiser or sunscreen it can last me for ages. However, I would love to use all of it eventually - I just don't know where to start.

What do you do - do you concentrate on using one set of things at a time? Do you have a system where you rotate your stuff (e.g. Use Cream A on the weekends and Cream B on weekdays)? Or do you just go all out and open up whatever depending on your mood?

I have already shared some of these products with my mum and two sisters to keep supplies from overflowing(!) but I still have a fair bit left. This does seem to me like it could be a silly question but any advice would be awesome - thanks.
