You do not need special equipment to write (nor a degree) just a pen or pencil that writes and some paper.

You can write anywhere or on anything available.  No special journal or special places.  Anywhere.  No excuses.  All those specials conditions just get in the way.

I always carry two Bic pens on me (in case one peters out).  They are cheap.  No special or favorite pen.  I write in blank books.  They are plain notebooks.

I try to get different colored ones and always keep the most recent in the same place.  But if my “muse” is telling me to write and I am not near my journal I grab the nearest paper within reach whatever it is wherever it is.

I am not bound by my journals.  Again, you do not need special equipment to write.  No special degrees.  Just do it.  Everything else is excuses.
