I only like the smart pretty women. But I am not tall or handsome.
So what is helpful?
細心 - yes that's me!
體貼 - I was, but it did not help. Don't do it too much now
知情識趣 - I used to be like that but don't over think it
口才 - use to be too honest - which is not always a bad trait. Later on learn to relax and more funny.
Self confidence - I was not born with this trait, in fact I was so shy. But now I am quite confident most of the time.
Overall, if the woman is not interested in you, you can do 100% and nothing would happen.
If she is interested, you will be successful because she lets you.
