A boy

Okay, I found 2:

What you'll need: Shell, Yellow candle
Light the candle and hold it in your right hand. Say:
"Please give me confidence So I can be the best
I failed it once But now I will be better than the rest"
Pass the shell through the flame and say:
"May this be my lucky charm so my wish can come true"
Kiss the shell for good luck and pass it through the flame one last time and say:
"May my charm help me in all I do"

OR

Relax and meditate. Chant softly, getting louder for about three minutes and courage will come to you. Chant the following:
Burning flame,
Cooling wind,
Summon courage from within,
I call on all my strength and love,
Send me power from above.

I haven't used either of these yet, so I'm not sure how well they'll work.
