Keep in mind this history of scales while you practice.
Albert Einstein, "I live my daydreams in music. I see my life in terms of music.”

very helpful! I was taught to play both hands once octave apart for 4 octaves, major, and harmonic, melodic minors. Put emphasis on every second key for 4 octaves, than 3rd key, then 4th, etc. until the 7th, which helps for even sound. Also do octaves, 6ths, 3rds like the idea of broken 3rds,
have not used contrary motion regularly. I have integrated arpeggios since it really helps stretch. Have just noticed I have a weakness in my left hand, 3rd, 4th, 5th finger, so working on an exercise to strengthen coordination and strength there.
Sometimes, I listen to you tube while I practice these. The exercises take about 1 and 1/2 hours. I take a particular key each day, does not really matter which, octaves, 3rds, 6ths, in that particular key . And some various exercises to focus on my weaknesses. Use trills in "the key of the day. " I usually go through the number of flats, like will do c, F, B flat, E flat, etc, up to 6 flats, and then sharps.
