The Aeolian mode is the natural minor scale (minor 3rd, 6th and 7th). It’s simply a major scale starting on its minor 3rd as the root. In other words, the A minor scale is also the C major scale. They both contain identical notes. The Aeolian mode (A minor scale): A B C D E F G. The C is the minor 3rd, the F is the minor 6 and the G is the minor 7. And of course, all the notes are natural so if you start on the C(b3 of the Am scale) you have yourself the C major scale. But they’re not going to sound the same to your ears because the tonic (root) changes depending on where you start from.
But to answer your question about getting jammed up…it happens to all of us. As a musician you have to find ways to stretch yourself, to get out of the same rut. I could quote famous musicians all night. There are many ways of thinking about it. Music is purely sound and often times we get hung up in theory and practicing scales/arpeggios. Can you hear in your head what you want to play? Can you sing it? If you can sing it you can play it. Learn everything you can and when it comes time to playing forget it all (and just play), make music. Music is an art not a technique. But for practicality sake, the only way to learn a new scale is to practice it and then use it to write a song or create a lick. Improvise with it over some changes. What good is a new pair of shoes if you don’t walk in them and break them in? Put that bad boy to good use! 
) feel. I used this system to start out with a Dorian scale-mode “base”, flatting the 3, 6, and 2 as so desired. Not much of a user of the major 7 interval - I almost always prefer the minor (flatted) 7 interval. With 7-tone scale-modes in mind, using 5-tone Pentatonic scales only differs in regards to which intervals are (selectively chosen to be) omitted from 7-tone scales (ie, the 2 and 6).
