Spell difficulty

You should cast spells for the person not on them. That way it cant mess up or backfire. For the good luck spell your planning try casting it so they have good luck in their endevors or just good luck to go their way. Hope i helped

Sounds like your having more trouble with your own 'conscious' then magic. Magic is a knife, use it to cut or to hurt BUT have your intention CLEAR on what your doing......

maybe but I have no issues with giving someone luck. The person who I cursed really deserved it and it wasn't so much a curse as bad luck for a day. I noticed it was problem the first time I cast them.

True.

What is true

Perhaps you should try to gain acknowledgment before casting as you say them not knowing seems to have an effect on your success.

Honestly it sounds like a mental block, you are keeping yourself from success because of your subconscious association with this issue regarding their permission.

Simply tell your friend you'd like to send them your best wishes and would like to pray on their behalf.
This is not a lie as a spell can be looked at quite similarly to a prayer in several religions.

thanks guys the first suggestion seems to work

Actually all spells can backfire or mess up in some manner.

Keep that in mind before listening to someone who tells you a certain method is absolute guarantee.

Yeah agree now I notice that it has about the same kind of feel as whaen I cast on m self. Actually recently I've just cast spells on myself to avoid doing it to others. Instead of making a family member by less annoying I cast a spell that let me gain a kind of grasp on social situations and diffuse my cousin's crazy ideas. I think that that is probably the way I'll cast most of my spells

If a spell doesn't work or contstantly back fires on you, it just isn't in the will of the universe for it to happen.
