Clash between me and Dad's thoughts

Yea that right currently me and my dad is going through little rough patches. This is all due to the differences in thoughts. Everyday there is something happens that results in reticent. The clash is basically on the future goal for me. Actually I want to pursue my Post graduation from abroad while dad wants me to get in the government service. I really hate the government service. According to dad the government pays well and has the security in job. But in my opinion the government job is very boring and nothing to do. I want to do something extraordinary, if get in the government job then the life would be boring. On the other hand if I get the chance to pursue my Post graduation from abroad, then I could achieve my both goals of being myself and to be at top level. I can apply for government job after completion of my PG. Then there could be much brighter chance to get good designation and salary. If I join the government job these things can not be achieve. One of my main Moto is to make my dad feel conceit and full of vanity. Now I am in great trouble to choose one from them. I don’t want to hurt the feeling of my dad but what can I do in this complex situation. The only thing I can do is to wait for the final decision. Please god help me to take out from the troubled situation.
