Marvel at concepts

At this point I'm trying to integrate what I'm learning on my fresh course on ethics (Mussar) and what I know both from previous knowledge and experience. In science I learned not to be original except for the discussion part which was my prefered part. Originality I see as the fringe of knowledge, where knowledge has no shape yet for us to understand it. I guess like a child I like to marvel at concepts.
Is the meaning of the word that I think it is really true or is the truth slightly different? Would another shape explain it better? I like to compare my ideas to that of others.

Juggling with selfishness

What I regret most is that I've pushed others away and chosen to be selfish. It is healthy to put up boundaries between myself and others, but at the same time we are a unity of souls. I tried to retract from this. This paradox of the tension between healthy boundaries and healthy unity puzzles me. What is my place? Am I conscious of the world, am I humble? It feels as if I'm juggling with this in relationships and when I think of world news e.g. on poverty.
How can I be with boundaries and less selfish, open to the world at the same time?
