Dependency on Krishna in every situation every time every moment makes the difference. Even at workplace. If we rely totally on our strength - may be our intellect or influence or wealth or words or deeds in every activity, we may get disappointed looking for the positive results all the time. If you take the example of Duryodhana, he was puffed up with his strength because all powerful warriors(who never got defeated in battle) were on his side. He was certain about victory. The pandavas had only limited resources, but their refuge was only Krsna in any circumstance.  Positive or negative outcome, if we are dependent on Krsna we will be free from attachment, fear, anger( BG#4.10- http://vedabase.net/bg/4/10/en1) and that is the way to liberate our conditioned consciousness. We are not changing our activity but the consciousness. Both Pandavas and Kauravas performed the same act of fighting but the cause and consciousness was different. Pandavas also lost their sons and soldiers in the battle. In my personal realization, when my spiritual life (chanting, controlling senses and mind, surrendered humble consciousness ) was better, I was able to tackle the hardest problems at work or at any other situation with less anxiety about results. It's like we associate everything we see in the world with Krsna in order to remember him as we perform our duties.(BG 6.30

http://vedabase.net/bg/6/30/en). Jatayu the bird who fought with Ravana to save mother Sita was a failure in his attempt but ultimately He was recognized by Lord Ram for his service. The Lord even performed his cremation with His own hands which is victory!!!

If we change our world inside, the way the outside world interacts with us will be certainly different. Many devotees have had those realizations even when dealing with outside world, how Krishna reciprocates with us via every person and every situation. Krishna is controlling the wanderings of all the souls in these machines of body life after life by giving them these facilities of body mind senses and material nature according to what they deserve. Not that he is doing all the activities that the soul desires nor is he responsible for the reactions of our actions. He is a facilitator, observer & one who sanctions.(BG#4.14 - http://vedabase.net/bg/4/14/en1)

Varnashrama dharma(assuming we are performing something close to it) is a gradual process to have regulated sense gratification and at the same time performing sacrifices to please the Lord. The ground rule is "Always remember Krsna, Never forget Krsna". This principle overrides all Vedic rituals, any rules and regulations. 

Krishna has given us the resources. Pulling the plug is about changing the consciousness & not the work itself. Currently our consciousness is contaminated by material motivations. The defect of Fruitive work is it makes us loose interest in devotional service. So we should rise above the mentality of Fruitive work(if I do this I will get that, according to Vedic rituals). (BG#2.44 http://www.vedabase.com/en/bg/2/44). 

Direct devotional service will be working for Krsna like building a temple or website or fixing a computer that is being used for His service, spreading His message to the world by preaching, book distribution, Sankirtan, Cooking for Him in full consciousness of Krsna. Amount of faith on the Lord also matters in Bhakti Yoga. I wanted to talk about direct devotional service to clearly discriminate what we are currently doing and where we have to get to. We are not there yet but we are taking every chance to do direct devotional services every now and then in every possible way even now.

For now we will see the facilities we get as His mercy and proceed(which is also a way to remember Him)  Eventually the goal is to attain complete unalloyed love for Him. Currently we don't have love for Him. So now we are practicing to slowly increase our love for God by this process of Bhakti yoga along with our duties of maintenance based on religious principles. Nature of this world is we got to do some work to maintain the body with soul. So we got to do some work anyway regardless of whether we like it or not, regardless of we are devotee or not devotee. There comes a time when we have to plan to reduce our varnashrama duties and increase directly serving the Lord in every way with spontaneous love at our hear. That's the final goal in our life we are all waiting for.....(BG#9.34 http://vedabase.net/bg/9/34/en1)
