Never tried a spell? It's not as complicated as you may think...
Sure some famous ones have massive rituals and steps, and can even require multiple people, but it doesn't have to be that hard.
Think of something you want to have happen, don't try something major, start small, concentrate... really want it, you can say it out loud or in your head, and repeat it until you believe it. You aren't trying to convince someone else, you have to convince you...

White spell: I really want mom to feel better tomorrow, heal, relax, you will be fine, your headaches will not bother you tomorrow...
Dark spell: Make "boy/girl" speak to me tomorrow, or run into me, so I can talk to them about... or hear what they have to say...
Try it, believe it, and make it happen...
