Response:

I sense from your letter a passive approach to your life. 

You seem to think that happiness and purpose are things that come your way or not.

However, if you take the position that happiness is something you realize and create from your present experience, then you will no longer be dependent on anyone else for your well-being. 

Follow a spiritual practice or meditation technique that will give you direct access to your inner creativity and strength. 

Then find channels of activity to express that life energy with others and into the world.

It can be almost anything that you love and are good at. 

When you start doing that, happiness will be the natural outcome.

Love,

Deepak
