1. Play it by ear. Pick just one scale pattern or sequence and play it until you have it memorized. You should be focused on memorizing how the exercise sounds rather than memorizing the finger pattern. Once you have it committed to memory, start to recreate the exercise using different areas of the fretboard. Use different fingerings, play it in higher or lower octaves, use only 1 or 2 strings...try to utilize the entire fretboard. The key is to not worry so much about the fingerings you use and to focus more on recreating the scale pattern or sequence by ear.
2. Use different rhythms. Learning to play scales will be of little use to you if you do not explore different rhythmic combinations. Learn to use rhythm to add to your expressiveness and create truly unique scale passages. Think of how rhythmic fluctuations in everyday speech can drastically effect the way a message is communicated and perceived.
3. Experiment with different articulations. Hammer-ons, pull-offs, and vibrato are just a few articulations that can really change the way a passage sounds. And let's face it, strings bends are one of the coolest and most uniquely expressive tools that the guitar has to offer. Practice adding whole step and half step bends throughout your scale patterns and sequences
