Re: plz Pray!
having concept in mind is different then its execution. therefore u actually have to file the petition (as dua in this case).
sometimes u also get to imagine negative aspects of ur desires, which doesnt necessarily means that they actually gonna happen. (well if u see negative aspects than its good cuz u may further pray for urself n for others ).
having desires in heart or in ur mind may be use to check pureness of your intention. that is y kidz are asked to make dua’s (or general consensus is “bachoon ke duain jaldi lagti hain”)
if u can not use ur tongue then use tears. but always start your dua with hamd-o-sana’h of ALLAH SWT & Harzat Muhammad PBUH. be cleaned, wuzued, face towards Khana-e-Ka’ba, look down, show ag-ezi, make connection with ALLAH SWT n pray. 
p.s. i will post more. but it will be better consulting any successful alim-e-deen n ask him/her’s way of making dua.
p.s. otherwise make a dua k app ko dua kerna ageya.
