We can't predict what will happen in the future while we cn continue to take action for a thing which will be better than to anxious or worry about the unknown future.

I know what I am anxious and afraid. I am afraid of the result that is not my expectation. I am afraid of it will be a terrible result while I spent so many times on it.

Think it again it becomes more anxious than before. Just do it which will be more relaxed it helps me to focus on the thing rather than to worry or afraid.

It doesn't matter it is your choice and you are willing to do it just accept the unpredictable result. Before that just pay more attention on the thing. That is great for me.
