It's ok to not have structure, but if you feel that the way you are leading your life is not working, then perhaps it is time to change.

I found that, when I was feeling overwhelmed, it was because I was not making choices.

Or, in other words, I was not saying "No" to enough things, so that I had too much on my plate.

I found that choices were hard to make but, once I started simplifying my life by removing elements from it, I started to get a lot more focus.

That focus allowed me to find the motivation and direction that I had needed all my life, but which I never thought I was missing.

Feeling unsatisfied with one's life can really be a great blessing ;-)
