I think the best way is to start slow and basic. Start with C major one octave on both hands. If you can do that then you can move along the circle of fifths to G major, then D, etc. I would recommend you purchase a Hanon scale book as it goes over what I just described. Once you get the basics down then you can move on to different modular scales, blues scales, pentatonic, etc. Also don't forget arpeggios. 90% of music that people consider difficult or hard are variations of scales and arpeggios.
