Don't be afraid of taking on responsibility. It's where you find what sustains in your life. You can take on too much responsibility; you have to be cautious in that regard. But that's a less common problem than not taking on enough. A lot of the things that people regard as traps are actually the means to their life.
You know often young people are afraid of commitment, for example, in the context of a romantic relationship. And because they feel that that's going to interfere with their pursuit of something more valuable.
That's just not the case. You're not going to find something more valuable in your life than a committed relationship with someone you love that sustains itself across time.
Once people have established their identities, they are ready to make long-term commitments to others. They become capable of forming intimate, reciprocal relationships (e.g. through close friendships or marriage) and willingly make the sacrifices and compromises that such relationships require.
If people cannot form these intimate relationships, a sense of isolation may result; arousing feelings of darkness and angst.
