how to make a good friend

I have many friends. There are friends who i met in high school elementary school and college. But they are not always good friends. Making friend is important. but we should watch out when we make a friend. Because they can influence us so much. So I've got ability of making friend.
First, i look for a personality of them. It is important that their personality matches mine, not too tough or easygoing person.
Second, i look for responsibility if they have responsibility they will not make a problem. For example, when they doubt me responsible friends won't betray me.
Last, i look for diligence and confidence people who are very diligent and confident do not waste their time. I don't like lazy and delinquent people.
These are a few kinds of points that i see when i make a friend. But the most important thing is "feeling". I'm not a robot. So i cannot think all kinds of these things whenever i meet people. And sometimes i feel good with them even though they don't have these "things"
In conclusion, I have judgement in my mind when I meet people or friends. This solution makes me sound like a cold person. But I've made good friends with these standards.
