Try to stand out from the other guys. Do not smoke, do not drink, do not swear obscenities. At a young age, many people want to appear older and resorted to such methods. But a real adult and Mature man distinguished't quite do it. Be gallant towards his beloved. Help her put on the robe, open the door for her. If she has a heavy bag, help her bring things home.
Do not play a role, do try to become better and smarter. If you will be posing like a tough guy, she will see straight through you. Be natural, then you will have more chances to achieve a reciprocal feeling.
Always look tidy and neat. Try not to wear outrageous clothes, because you don't know what style you like your beloved. Look simple and stylish. You can wear jeans with a Polo shirt or sweater. But do not wear pants with the crotch at the knees or too tight jeans. It is not for everyone and often looks ridiculous.
Develop, become better than you are. Exercise, read a book. You need to stand out from the General mass a beautiful body and good knowledge. Then you will be able to earn the love of even the first beauty school.
Be a little cocky, but don't go overboard with feeling. Girls like strong and reliable men. Become for her a stone wall, behind which she can hide in any weather. If you are studying in the same class, help her on the test and its answers from the Board. Let her be written off, but occasionally asking for something in return. For example, to spend the evening with her or to walk her home. Don't be too arrogant, but to become a humble servant is not worth it.
Find out her tastes that you have always been a topic of conversation. You should not always humor her, agree with her point of view. But you just have to know what she lives.
Try to spend as much time as possible, but don't turn into her girlfriend. Always be a person, a man who will support her in a difficult moment, but do not impose it constantly.
To know the girl better, talk to her friends.
