Yes, there is real power in magic. However you cannot just simply read books on the subject, it must be practiced to be fully understood.
The learning of magic takes time and discipline, much like any other pursuit. Unfortunately, it is not as simple as harry potter, where a wand is waived and *BAM* instant effect. It takes time to understand just what it is your doing, and adjust your mind to accept feeling from your whole mind, not just rationalization.
If you are really dedicated you should choose a focal point. For example, heating water with the mind. If this is your goal, then study the elements of water and fire, grasp a basic understanding of what makes the water heat, how fast, ect. You may find that even simple tasks such as this are much more complex than they would seem.
Honestly, it's the first success that's the hardest. After that everything becomes much easier with a clear mind free of nagging doubt in your subconscious.
