What I think you should start out with is getting to know the Energy of the five elements (fifth being Spirit) before you go on to do Elemental Spells. The Energy for these spells are very important and will increase your chance of success when doing these spells. What I would suggest is to find a simple energy spell on this site and summon 'regular energy'. All five elements have energy that are relatively different from each other. Practice summoning the regular energies everyday, until you can summon it without doing a spell. When you have succeeded, begin summoning energy from one element at a time until you can summon it at your will. I would advise you to start with Spirit (Akasha) first, since it is the Element that connects Earth, Fire, Air, and Water. Then once you learn how to summon the Spirit Energy, begin to try to summon the energy of the other elements (one at a time, do not rush. It is easy.) Go outside for Earth and Air, and for Fire and Water, just take a candle (fire) or a simple bowl of water. It is very easy and it only took me about one full week to be able to summon the Energies.
Once you have perfected this, you may begin to do beginner Elemental spells, like summoning a small gust of air.
The Energies are very important. You musnt forget Spirit. It is in all of us. Meditation is good for summoning Spirit energy.
