does being competent in L2L make your life happierD

in the last weeks I have read, reflected and talked a lot around L2L - and right now I have certainly many more questions than clarity. But I suppose that's good so although it feels a bit heavy. Some of the questions and reflections are:

If we consider L2L to be one of the essential "life competences" the question is:
How do you lead your life differently when being competent in L2L?
Can you lead a happier life then?? or a more successful one?
Is it anyway potentially relevant for everybody in the world to be L2L competent?

And - how do you notice that you have increased your L2L competence?? Meaning what are the indicators?

And last but not least - what is the relation between L2L and self-directed learning???

pfuuh, but still exciting - by the way found a good and useful book published almost 20 years ago(!) in the US: Learning to Learn across the life-span from Robert Smith and Ass.. Very useful articles from people like Maurice Gibbons and Malcolm Knowles which are still core references when writing and talking about this topic.
