Humanity can only be served by being unbiased. People often follow “give and take approach”. That’s wonderful. No one says you shouldn’t expect anything in return if you do good for others. Expectations arise. That’s part of human nature. Besides, when you receive, you feel like doing more. The more you give, the more you get. The more you receive, the more you give back. That helps build trust.
Having said that, the problem is not when your expectations are met, but when they are not met. It occurs because somewhere in our lives we become biased and start favoring/receiving those we love and care about the most. We become biased without thinking it’s there until it’s in the “give and take approach”. As soon as those expectations begin getting stretched, we lose our inner core of love which is based on unbiased human traits.
Because of this, one must be unbiased in order to serve humanity. For example, if you love someone or something, first you must separate yourself from that person or thing at the mind level. Then, you must see the situation as being unbiased. You should question yourself every time you seek to serve people as a whole, “Am I biased or unbiased as far as world empowerment is concerned?”
For example, being a writer, it’s my responsibility to write stuff being unbiased in favour of humanity, with care and love. This is so that when this message reaches my loved ones, they don’t see it as personally, but see the motive. If you serve the nation unbiasedly, even if no one is standing behind you appreciating your work, the hearts 
of people still appreciate it. There are people who may not be physically present for you, but their love speaks to your heart. Unconditional love is felt within.
Serving humanity requires unconditional love. We still share unconditional love and care for each other. However, we don’t recognise it until something big mis-happening happens to all of us. Haven’t we seen cases where two neighbours fight with each other often, but when such natural disaster hits as earthquake, they come closer helping each-other forgetting all their anger instantly? That’s us. That unconditional love is there beneath in our core surface. I believe all of us have this. Unfortunately, we don’t dig ourselves that deeper on daily basis. If we do, this entire world become a paradise indeed!
