i can give here example of Barrister Itzaz Ahsan which is a big name in influencing personalities of Pakistan......jb itzaz Ahsan barrister bn kr pakistan aya to log khny lgy k barrister banana konsi bdi bat ha css kro to pta chaly k koi imtehan pass kia ha....so he decided to do that.....he cleared this exam with flying colors and come in one of the top goups but he had not joined this service because he knew that i can do better in other field....Today we know he is enjoying everthing better than CSP officer.....so CSS is not the end of world but it doesn't mean that we should not go for css...Try your best if you selected then well & good if not then "teray agay asman or bhi hain"
