If what you are doing right now is not working and you're frustrated, STOP, and do this instead…
Doesn't matter if it's 10 minute straight, or a minute 10 different times a day, but each of these should altogether add up to 10 minutes. Don't overdo any of this, you don't want to exhaust yourself, you want to enjoy each day of your life as best as you can while putting just enough time consistently each day into these practices:
Spend 10 minutes a day imagining a different self, superior to your own physically and mentally, and identifying with / imagining that that is you, and feeling that you becoming possessed or the possessor of/by this form/mentality. You may continuously adjust and improve upon your imagined better self, start with a very basic outline and go with that, and then add more details later.
This simple practice will help you change your physical form dramatically and strengthen your mind.
Spend about 10 minutes a day memorizing an axiom or learning about the qualities and attributes of God. Once you know all 7 hermetic axioms and can recite them by heart, endeavor to imagine the actual pages they are written on, such that you can see before you clearly the page on which the axiom is written.
This simple practice will establish firmly the basic, axiomatic truths and principles in the mind, as well as strengthen the memory dramatically and make further reading and memorization of any texts thereafter much more efficient. You will be able to recall texts both visually and non-visually. This will enhance all future study.
Everything you learn about God will strengthen your connection to God and your ability to center your mind in his power.
Spend about 5 minutes a day either concentrating entirely on one thing, or relaxing yourself completely and focusing on nothing at all, letting all your mental and physical processes become automatic and relaxed.
This will strengthen your focus, your ability to concentrate, to meditate and work on thoughtforms without them dissipating due to wavering concentration, etc. and when you decide instead to relax this will help you learn to do the opposite which is really important, like how you don't want to be manually breathing all the time, as whatever you have to do consciously you waste more energy doing.
I still am waiting for God to tell me about regeneration and also fighting anxiety. I have some speculation in my mind as to how it might work but I do not know yet. Maybe in the case of anxiety, discharging all my negative energy will do the trick, although I have so much of said energy that it will cause physical manifestations and some terrifying stuff to happen, especially if all discharged quickly and at once.
I personally can concentrate on just one thing for an hour at a time or longer, really incredibly long periods of time.
I think God wants me to be consistent in doing these things every day but not overdoing any of it, spending most of the day just living my life. IDK.
