We need to live our life according to Islam If we want happiness forever

I wanna live my life only according to Islam. Our real life will be in after here, so I dont wanna waste my short life with full of worldy enjoyments. I am currently willing to marry someone who is also having same purpose of life with me. I am not looking for Mrs.Princess nor I can say that I am Mr.Perfect. Currently, I am studying in first grade of university however I am willing to relocate and maybe keep studying in that country where I moved.
