Listener question: how do I let go of the thinking?

Listener question: I still have the thoughts that say for example, "Once I cure this health problem, I will be "happy" or "feel better" OR once I find the right partner OR once I get a job writing in comedy" - Like those still run in my head. And then I just wondered... do I stop trying to cure the health problem? Find a partner I enjoy or try to change careers? 

Like.. from my understanding of your work, I am just going to do what I do - if I have a fascination with health, I will try and improve my health... if I desire for love, I will be looking for a partner, if I have a love of comedy, I will try to be able to do more of it - even my love of reading about these principles I will just continue to do! but how do I separate my doing from the belief that any of it will somehow improve my life? Essentially, how do I let go of the added thinking on top of it?
