I was a really late adopter of smart phones and for this reason have struggled with apps. Also opening my phone presents so much temptation to go on social media.
What I have found incredibly useful and appeals to my creative side is Filofax. They do different kinds of notebooks and some of them are not too ridiculously priced.
The great thing with them is the pages are moveable, either in ring binder format, or in spiral bound format, in both of these you can reorder the pages. This offers lots of flexibility.
You can also get erasable pens. This I love as it means pages can be reused, lists can be tidied up etc.
And the paper is nice enough quality that it feels nice and I have a quiet pride in maintaining the system.
I bought some solid sticky tabs and a labelling machine so I can create my own sections - I have a tab for each month and a weekly plan. Tabs for a few projects.
You can buy plain or different types of pages on their website so it's very customisable. I have the fold out monthly planner so I can see at a glance what is going on and I've stuck it on the notice board.
Like any system it's only as good as you using it. But so far it's been helpful and easy to put back together when I inevitably get in a pickle. Having a daily/weekly review routine etc.
There is also a Filofax Facebook Users group which in a sad way acts as accountability for me in using a planner! It's a vaguely cult like group for Filofax lovers. People share there organisation layouts and review systems.
Day to day I use Alexa a lot and have one dot in each room.
