feeling so stuck with my mistakes

so like i keep making the same dumb mistakes and everyone says 'just learn from them' but how??? wait is this a stupid question lol like i tried making a spreadsheet for my vocab slips but then i got overwhelmed trying to categorize them by action or direction or whatever and now i just stare at it. idk should i just ignore the mistakes and hope they go away or am i doing this whole forward-thinking thing wrong??
