I totally agree with you as I am also someone who writes down everything on paper. I have tried some phone apps but it's just not the same (the best one in my opinion was Trello, that can also be used on computer).
I am using a bullet journal system for about 3 years now , where I have everything, from daily to do's, short term and long term goals, events, birthdays, movies to watch, books to read and all kinds of lists, Steemit ideas and a lot more and I honestly don't know how I would go about my life without it. :)
I may need to transfer over to this method of journal as well. It would be awesome to have everything in one place. I use a blank lined, hardback journal at the moment, but I like the idea you shared.
That would work great for a bullet journal since all you need for it is a blank notebook of any kind and a pen. There is so much information about it online (Youtube, blogs, Pinterest, official website) since this method became very popular.
I hope it will work out great for you, if you decide to try it out! Good luck! :)
