There are some people who are able to put their needs first and to be there for others when it is possible. In this case, it shows that they are comfortable with their own needs and don’t feel the need to ignore them.
Just as there are going to be others who only feel comfortable when they are taking care of others needs. As a result of this, one is going to be there for others but they are not going to be there for themselves.
To have needs is part of being human, and this means it is not something that one can change. What is going to cause problems is when one doesn’t feel comfortable with their needs and always ends up putting others needs before their own.
