from Thich Nhat Hanh’s book “How to relax””
In order to be happy, we need first of all to let go of our ideas of happiness; we think that we must have this or that to be happy, or that we have to eliminate this or that to be happy. We think that we have to have certain conditions: We have to have this house or this care that person to live with us so that we can be happy. We have these ideas of happiness. If we haven’t been able to be happy and joyful, it’s because we’re caught in our ideas. So we have to be able to let them go. Our idea of happiness is the main obstacle to happiness.
