You'll have more energy as you advance, your regular habits should help with this.
Chakra Spinning daily will raise your natural energies.
Cleaning will remove blockages that prevent energy flow.
Hatha Yoga improves many things.
The SaTaNaMa meditation will help with literally everything.
The God Rituals have a theurgy effect that will develop you.
If you genuinely need more energy at a given time, you can raise your energies with SATANAS or any other energy raising methods, and since you are not doing a working, you can program them to just not dissipate.
Something like:
SATANAS for, say, 3-5 rounds. The vibration here should be long and focused, taking up a complete Yogic breath.
You should be focused on feeling and raising the energy, so a light trance can help here.
Affirm, for the same amount of times as the vibration:
"I am raising powerful energy, that is safely and positively increasing the natural energy within me, permanently."
Then simply sit and do not move to not let the energy dissipate. You could practice void meditation here, or just stay in the trance in order to get extra training done there too.
You can make this into a habit until you no longer need it, due to your other habits.
