Is it true the more desperately you want something, the less likely you are of getting it?

I think this is true just because everytime I wanted something so badly and pushed to get it, I never got it but the moment I stopped pushing for it, it just happened.

I think I am going to stop wanting things to happen so badly and if it happens great, but if it doesn't then that's also great. It just wasn't meant to be.
