I made my own starter a couple weeks ago, flour and water and left on the top of the fridge.  I have been feeding the starter each day for the past two weeks.
I have not discarded any.  Not one of the days.  Now the more I am reading I see I should have discarded half of the starter before each feeding.(still not clear if that is only the first week or always?)  Each feeding I did the same amount of flour and water like I did on the first day, regardless of the growing amount of soupy starter in my super large jar.  It has smelled fine, I have even baked with it a few times. So now the more I am learning I feel like I should discard most of my super large jar... and start feeding a small amount of the starter, and doing the discard/feed that I am reading now.  Do I have to start over or can I use this?!  TIA
