What would you prefer to write in a notebook journal or on your smartphone or laptop or pc computer?

Hey I'm 24 year old male who has decided that I wanted to start writing ✍️ in some type of journal and write stuff out from my day to day and also would like to write stories for fun that I can make up and tell my niece and nephews and also write down jokes that I can tell my friends and family so for me being a young adult male what would be more appropriate to use my iPhone 7 or a? Notebook with line paper or a notebook with no lines? Please if your going to comment on this help a brother out and be nice and polite.

Notebook with line paper?
Notebook without line paper?
iPhone 7 an app from iTunes?

I would suggest grabbing Evernote for your phone, that way you'll be able to access not only from your phone but from your computer as well, you might want to attach pictures or sound clips or even videos. It'll also be safe if your device get's destroyed or you switch from Apple to Android.

You always have it on you, easy to organize - no contest in my mind.

Well, firstly, you should learn the importance of punctuation, especially commas.
secondly, spelling is vital. Learning to use "you're" instead of "your" (when appropriate) will help improve YOUR grammar.
you can jot down short notes in your phone's Notes app, but when you want something permanent, using Microsoft Word or a Notebook is far better. I prefer a computer, because if i make a mistake i just have to retupe it, it has spell check, and it just looks nicer and is easier to read.
if you go with a Notebook, get a ruled (lined) one. Otherwise your lines of text may eventually start drifting at an angle…
