For instance, I have learned how to move my body when playing so that I developed an internal clock, helping me to be on time.
Internal clock - that's just it
I swear that I can't really make progress in a technique unless I can feel the groove with it.

That's one thing I say to my bass player, he seems to play very stiffly rather than finding a groove, MOVE WITH THE MUSIC!!!!
Yeah it's a hard concept to try to orate to someone.. they gots ta feel it !!
The interesting thing is that groove also stems from the concept of harmony. When we groove on our own we're in harmony with ourselves. Playing with others requires us to harmonise our natural rhythm with theirs. That's why jamming with people is great, especially early on in your guitar journey.. you need it.
When you play with others, you have to harmonise your groove with them, even if they play too fast or too slow. Good musicians know how to adapt to others and compliment them instead of rigidly maintaining their own rhythm (even if it is perfect) and allowing the others to stray out of the groove. However, if the other players are unable or unwilling to harmonise their groove with you then you might not get past it. It's quite an interesting concept, the idea that every time we play with a new person we have to harmonise our groove in a different way.
I'll give you a personal example. For years, I used to be very stubborn about timing. If a drummer played a fill that slightly slowed down I would ignore it and make a point out of maintaining the timing on my guitar so that it would be glaringly obvious to the drummer when they went out of time.. I'd also give them 'the look'. Thankfully I've grown up a lot since then.
Later there was a period where I used to go and jam with this drummer, just me and him and for the first time ever I really, really listened to what he was doing. When he was doing a fill I'd follow him and be determined to be on time with him when he ended the fill so we could go into the next riff together. That was my moment of 'enlightenment.' It doesn't mean the drummer was right and I was wrong because drummers do sometimes alter their pace when doing a fill and sometimes they do mess up their timing but it meant that there was no disharmony and that was the important thing.
