Practice routines are absolutely proven to work. Design the one you use for the results you're trying to get. Make it a routine, not just "whatever-whenever" for best results. It takes 6 weeks to build a habit, so diligence is required. Just playing along with youtube or a CD is good for learning songs, but less good for overall musicianship. For that, you need some fundamentals.
I'm from a classical background where everything is written, but now I play BG and need to be able to play lines by ear on-the-spot, so I try to make my fundamentals 60% of my practices at least. If you have solid scales and arpeggios, you won't even have to think about which notes come next; it'll be right under your fingers every time there's a chord change. There is study material for all of this stuff all over TB.
Here's what's been working for me (practice routine, 60-90 min/day at least) in the last 6 months since I switched from DB to BG. There's almost always something else to add to the list for a day or a week, but these are the basics.
Every day - all 36 major, minor, and blues scales, for two octaves, up and down. Finger exercises for stretch, shift, and speed. Run my two-dozen-or-so practice licks a couple of times in a couple of keys, and do some "groove practice". All of the technical stuff is with a metronome, differing tempos (80-180) and durations (w-h-q-e-s) in nut position.
Every other day - same scales with "box" positioning, arpeggios and runs for a bunch of chords, for two octaves, in the common keys. Also run all the songs that are on "current" set lists (hopefully without looking at the changes) and hit one new or technical song/line/phrase/pattern a couple of times, by ear if possible, but with a lead sheet or play-along if it's complicated.
Weekly (usually Mon or Wed) - Sheet music reading, usually jazz or some flavor of folk, with at least one new or technically difficult song. Vocal practice, mostly songs but also some scales, interval exercises, and intonation practice at least
Weekly (usually Tue or Thu) - Learn a new bass line or lick from a non-preferred genre, then "library" work. My current play-along-on-shuffle list is maybe 3h long and has all the stuff that I might play again somewhere, bass lines I need to refigure, covers that I should know, songs somebody challenged me to learn, complicated arrangements, blues and jazz jam tracks, stuff I want to talk a singer into, music for try-outs, etc.
My needs are specific to me; You can do this type of thing to address your needs. You could even start TODAY with quick one-octave major scales on all the natural tones as a warm-up before you play anything else.
