Balance

They say happiness depends more on our inward disposition of the mind rather than outward circumstances.

They say if we allow someone else to be our source of happiness, sooner or later (more likely sooner), we will drain him/her out. 

And, what if he/she dies before us?

In the end, we only have ourselves to depend on.

Of course I think it does not mean that we should not find joy in the company of others.. but there is a fine line/balance between both- and to find that delicate balance, is my current life mission.
