To avoid anxiety I recommend to develop day by day.

I think this is a great recommendation. Many times we don't live in the present time but in the future, imaginating (for no reason) things that don't necesarilly are going to happen.

I think we all should be careful when we meet people and don't trust too much before we can know them and figure out if they are really worth trust. This means we have to take time. And if we don't feel all right next to some people, we should not stay nearby.
