If the thoughts are useful or workable to you, you may use them.
And if they are not, then you may notice them and let them sit there. This also aids in becoming flexible and taking effective action.
An explanation by Gabriela Sadurní Rodríguez on The Psychology Group channel about cognitive defusion. Looking at thoughts rather than from thoughts. Noticing thoughts rather than becoming caught up in thoughts. And letting thoughts come and go rather than holding on to them. In the words of Jon Kabat-Zinn: You cannot stop the waves, but you can learn to surf.
