Getting backing into or for the first timer can be very anxiety provoking. I like the advice above "to be Sincere" that goes a long ways. You can develop your mind set and create more confidence. The techniques that are used have been around since the beginning of time. Harnessing them is magic.
First let me share that you must believe in yourself. Check your self esteem. If you aren't happy with you, it's like wearing a sticky note on your back that says "ignore me". Secondly, you need to focus on just being you. It's when you try to impress people that you turn them off. Be more of you naturally and you will attract the right person. Nothing is more destructive than trying to be someone you aren't. If you need coaching support, visit my profile page to link to my website for more information. Hope this provides value to you
