Doubts. Many doubts.

I can tell you know that magick will not allow you to teleport, read minds, fly, etc, all of this is fantasy. I suggest you looking into the basics and the reality of magick, that way you can start having successful castings, rituals, etc.

Yes, start with the basics. Learn Meditation first; then everything else will follow gradually. The example I gave of bread is a simple form of magic; there is a lot more to it than that. But it will not work miracles like flying!

Caesar, a lot of great advice has already been given.

One of the most common definitions of magic is change in conformity with one's will.

In my opinion, the greatest work one can do with 'magic' is internal, not external. As Brysing pointed out, it all starts with meditation. There are so many types of meditation, from quieting the mind od cluttering thought to mindfulness to self-exploration and more.

Through meditation, I began to understand myself at a level to work on some major flaws. I did couple that with actual professional advice. And it has resulted in some significant change -- in accordance with my will, to be less subtle about it.

Well with that being said, what would I be able to do while using magic, then?

Yours, Caeser.

Magic is "change". But not always change of material things. It can also change your attitude to life. The way you look at the world. Changing your immediate environment.
Magic, really, is "enlightenment". And most of it comes from Meditation, "deep thinking".
It allows your subconscious Mind to "take over" your conscious Mind. Your conscious Mind sees,hears,and touches, only what you want to see,hear,and touch. Your subconscious is aware of everything. It misses nothing! Everything you have ever seen,heard,touched,read, is locked away in your brain. When you Meditate, and release all that hidden knowledge, you will be stunned at the result!
