I am the youngest and I hear similar words about " humongous responsibility" to be positive from my sister who is the eldest.

As a younger sister and being a self improvement enthusiast, I feel this way:

You don't have have the humongous responsibility to be positive for the sake of other siblings. However you do have the responsibility to be positive if it nurtures and enriches your soul.

That will give a huge shift in your personal energy.

Your siblings will get the vibe
I am glad that my sister truly loves her. She is enriching her soul by working on her Being, not doing for us all the time.
Your siblings will become independent, confident loving Beings.
Your conversations will be more meaningful.
You and your siblings will learn to be there for each other only when you both truly need each other. It could be being physically available, mentally available, or emotionally available.

You will also notice that you will give space to your siblings to develop on their own..


It may sound preachy. But it has worked for me and I thought I will share. Thank you so much for reading.
