fermentation

Fermentation really interests me, I mean it makes stuff taste awesome. No no I didnt just down alcohol :P I just ate sour dough bread! Yummy!
After easily making idly but struggling to make Yogurt, I am wondering what would happen if I add yeast to milk :-D Well I vaguely knew that yogurt fermentation is bacterial and not yeast.. but then I also had a thought that fermentation is fermentation.  so .. this link. It provides all possible answers to all possible types of fermentation.

basically, Bread Idli etc are yeast fermentation, so u can use the bread  yeast to ferment Idli, but Yogurt is bacterial, lacto bascillus ( Oh comeon! I knew this, Science blindness infected me for a short while ) All the sour veggies like Kimchi are bacterial. 

conflict between inner and outer

Should I spend all the effort on the inner improvements because that is what is real?
but the lack of improvement/progress  in outer world is scaring me, should I put some effort there as well? Especially when I see others improving and going further.
My heart is not in it, but is it possible at all to focus on the inner world while being worried about the outer?
At the current state of development I am in, is it possible to let go of the outer like some people seem to have done? Like the monks, like the happiest man in the world etc?

There is once aspect of inner development which I am not concentrating on at all, that is loving kindness and compassion for others and also the helping and karma yoga part.

The outer development can be in these areas as well - right? This will also help with inner development. Is this the solution?
I am really not braving the world and putting myself out there for anything, spiritual or non-spiritual. The focus on inner may be an excuse to avoid putting myself out there.

So this is how it goes, my mental state these days, the bliss of one month of yoga having long faded :D

The thoughts that my outer ego is pushing me towards are

Develop social skills
Start caring about the impression I give - i.e image
Network - attend conferences/shows - meet up people
Re orient career - apply for google, apply for higher post
Treks
Solo travel
Triathlon or some achievement
Yoga some achievement
Meditation some achievement
Teach yoga/Pranayama workshop
Show people :D - by being slim, by looking good, by earning more, by showing happier lifestyle
Good grooming, good clothes, make up etc - again part of image
Meet up and take tips from some people
