If you think cutting 'hair and remove pagg' gives you a 'good handsome appearance' as well as making one more eligable to fit 'in norms of society', without being too judgemental except on what you have said; then Bhai Sahib Ji you have obviously not been blessed with the correct mindest yet required to even start to become a True Sikh of the Guru and so your name fits you perfectly :D
In this life, for a Sikh, there is simply the Guru's way (Caring and Fearing what the Guru thinks) or Maya's way (What the World thinks. Maya is Guru Ji's servant that has the whole world lost in pointless things). All the points you have mentioned come into one of these catergories.
Even the justification you give of 'I am kesadhari 20 year old and I have kept my kes because :
To maintain sikhi of my future generations . I dont want to kill an entire generation of my descendants from sikhi saroop ' is unfortunately what can be seen as being an incorrect reason.
It should be out of YOUR Love for the Guru and the overwhelming desire to follow Hukam to please Guru Ji. This view which you have just shared is similar to the parents of yesterday who tell their children to keep their hair and not cut it. When questioned by their children why? Can only ever give simple and non meaningful responses such as because this is what we do, or because I have said, or it is bad to cut your Hair, and so on.
In the end when you die, the perceptions of the world will not save you, the strength of the bond that YOU have with the Guru will - that's if it's strong enough :L:
You should do Ardas for this in Guru Ji's Kamal Charan Hazoori for a greater love and understanding, because without this you will undoubtedly question your own Sikhi and Principles, maybe find out that you have not come to YOUR own true realisation and justification of why to be a Keshdhari. This is when Maya, like how she has manifested as a thought already - temptation, may turn into a action.
