Going to change my hair style

I'm getting sick of my hair style, must change it! Poor me! I'm still not sure about the shape of my face, round or square? Maybe there is too much fat to find out... I'm also worried about the cost, it mustn't be cheap because it's in Singapore. Haiz... So difficult to survive! I hope I can work as soon as possible to get my own money that I can do whatever I want to do!
