You could practice ghosting with the superimposed lines exercise like I do.

Here's this post by Uncomfortable that might help you with overcoming any hesitation that you might have with making marks. The important thing for you to realize is that hesitation while mark making is useless, you need to be comfortable with the idea of making a wrong mark. When you're at the point of making the mark, you'll have to let go of hesitation, since you're well past the point of correcting any mistakes that you could be baking in the mark. Its hard. Its something that I am personally working on, but its possible. You need to put in conscious effort towards it. At the last point, you simply cant trade the confidence of the stroke for its accuracy, a confident stroke is way easier to work with and account for down the line as you develop your piece. You just need to forcefully shut the hesitation down because it will do you no good.
