You mean like you want to study but have no energy to motivate yourself enough to open the book? That you could spend the entire day saying to yourself that you gotta study, but spend the time laying on the bed & staring in the ceiling? If that's the case, I recommend you start meditating and build a routine around the meditations - come form school, lunch, aura cleaning (high schools have enough negative energy to kill a bull...), half an hour of homework, few vibrations of runes such as MANNAZ, KENAZ, SOWILO etc. Just look it up on joyofsatan website & do whatever suits you best (SATANAS & SATANAMA pack quite a punch of energy) don't forget to add affirmations (eg. The energies of MANNAZ are affecting my memory and intrlect in positive manner for me - you can change whatever you want, just don't forget to add 'in positive way for me' somewhere in there)
You can also use the power of runes to secure yourself a place in whatever university you wish to apply for. I believe SATANAS would be best because you can use it for anything, you just gotta have good affirmations (present tense (I am accepted to *name of the school*), short, simple & contain 'in positive way/manner for me')
Oh and you can also start a Mercury square in February if you want to boost your intellectual skills (lydia made a post about it, basically it's best to start it on Wednesday this February (8th, 15th & 22nd if I recall correctly), vibrate the mantra for 64 days & that's it (ok you gotta check on joyofsatan website for how many times you gotta vibrate the mantra per day & 50 is a big number but it's doable))
Ok this is getting long... Other people will probably give better advice, but I hope this helps (ps you can search for 'joyofsatan runes/planetary squares/whatever you want to study bu can't find on the site' )
