Never give up and don't settle

The studies of communications state that the more filters a person has the harder it is to get close to people. Most people have higher level of filters for people depending on what they mean to them in their lives.

Lowest acquaintance

In the middle family
Highest best friends or Lovers

Though it's good to have an ideal for who you want your future lover/spouse to be, it's good to cut back the list to the essentials. Pick no more that 10 and better yet 3-5 must haves you want your future mate to be like. excluding what most people should already be and that's,
emotionally, physically, and mentally secure and strong. Sadly many people and possibly including yourself, could be far below the level one should be to be stable and secure.
The problem is, many people start to look for a lover when they are in crises, depressed, or financially in trouble.
If someone does that, their filters go down and they become desperate. Then when that person becomes healthy and stable they realize they ended up with the wrong person.
DON'T DO THAT TO YOURSELF!

Now I am not saying you have to be perfect, or a Buddha/saint/ or something holy but one should at least be on the path of health and purpose.
