A nest?

For a senseless egoistic lass as myself, ego is my nest.

It comforts me, nurtures me, protects me from the external world. I could take a false impression of home in it, and thus keep myself from flying. 

When in reality, I’m only fooling myself. The only way to adapt to the changing seasons is by leaving your nest; flying away from self when the time is right. Perhaps the greatest obstacle in the way of your flight is the one of your making. The day I learnt this principle, I learnt to set myself free. 

The day I learnt to accept that someone else can be more important to me than my own narcissistic self, I learnt to love.
