Sounds to me like you might be going too fast. Try adding or creating some ideas now of your own by experimenting with some of the licks you have learned. For example, rearrange the notes of the lick, change the duration of some of the notes, pick one small part of the lick and repeat it before continuing, try to drag it out to last twice the length, or do the opposite. Anything you can think of.
Imagine you have a backing track with a 12 or 24 bar solo (just for example) but there are no such things as scales and your guitar is limited to only playing the notes you learned in the lick. This is all you have to work with, nothing else. You are allowed to do whatever you want with those notes, but those notes only. What ideas can you come up with? Restricting yourself in this way should help you find new ideas. You can hang on the notes longer, bend, slide, repeat, double up, vibrato. Spend 20 minutes or so playing around with that limitation and see if it helps you find new ways of thinking.
