Dislikedit may (or may not) take time for u to get confident when/in taking a setup. (confidence from experience)
but IMHO, it would help immensely if u have self-confidence to start with.
feel good about yourself; think positive.
think of &/or list all of your best attributes, successes, good past experiences - this will help u draw/accumulate self-confidence....Ignored
When the going gets weird, the weird turn pro.
