Your reaction to what happens in your life dictates what happens next.
If you are constantly being trown of by whatever is happening outside of you, if you are constantly looking for the proof of your manifestation outside of you, then you are a slave to your environment.
Manifesting is not about what happens outside of you, it is all about what happens inside of you. It is about the growth within yourself and the proof you find within. Once it is inside of you, the manifestation will be the result of that, outside of you.
