step by step, letter by letter, like Russian children))

I'll give the method i used to overcome this problem " Don't start with learning and memorizing the Alphabet " I started with knowing how each letter sounds and i began to learn words and know how it's pronounced and step by step i've began to know each letter and skept the first difficult stage and getting a good start with the language . i hope i could help you with that , and Good luck :)

I agree with Azygos - learning them in the alphabetical order is not an easy way. One method is to break them into 4 groups: Letters that are (almost) the same as in English А К М О С Т E Letters that look the same as English but are pronounced differently C Х Р У Н В Letters that look different but are pronounced (almost) similar to some sounds of English Б Г Д З И Л П Ф Letters that are completely different Ж Й Ц Ч Ш Щ Ы Ю Я Ё You can sign up for my Reading and pronunciation Intro Course and I will teach you how to pronounce the sounds and how to read in Russian if you are interested.

How long do you exactly mean ' short time' ?

simply memorizing them...no other way:)
