1: eat right , magic isnt particular unless the spell or whatever calls the specifics for it.
2: exercise because your body is a temple or at least walk more often because a body is the conduit for the soul and all energies.
3: practice absorbing magical energy you can meditate while thinking you're absorbing energy or the fast way by looking at the moon to charge your eyes when you think your eyes are charged to a certain point close them and imagine the power coursing through your body.
4: remove any excess energy so as to cleanse yourself especially if you been around bad things or people or as a means to control yourself from being a supercharged cell that attracts all sorts of bad things like succubus session or ghosts and demons or even worse another magic user. Which may be a psychic vamp.
5: try to use magic whenever you can so as to keep in touch with it so that it molds to your will more easily... I would suggest try super charging yourself after you put in place protection spells and charms also remember to enchant a weapon... after you super charge yourself for a month straight don't try to release it all at once but try to do spells everyday for the next month to get into better tune with it... or you can release it all and waste a lot of energy without doing something significant with it.
6:protect yourself and your loved ones give them charged necklaces or something and also put up a barrier to protect against anything that may intrude into your domain ... for example an old dead warlock will feed off your energy and those around you then become something other than a ghost...also enchant guns and bless them or curse them ...idk
7: always teach others and empower them with words of wisdom or other things even light fun filled conversations can produce wonders for an ego...
8:magically augment your body to absorb a certain elemental energy and you'll eventually get a sort of resistance to it...or make yourself light as a feather to escape or to fight with lightning speed.
9: enchant all your clothing with both protection and repulsion spells maybe power spells to always be sure you're protected outside as well as inside ... and while you're away from home.
10: seek others to try cola berating spells or something of that matter... me and my brother sometimes charge the other one up and the other realeases the power like a back and forth thing until both our bodies feel even... this is another way to gain more power.
11:find a place to practice other than your house because who knows when your house will become compromised.
12. Use all knowledge you have of magic and spells or inner enchantment techniques to grow in power ... then pass it on to others ... for example your children or somebody else's children so the knowledge will continue.
