Alhamdulillah ! It is a nice question by a brother or sister.
To my mind a muslim is supposed to take all sorts of preparations to receive the sacred month, the month of "R A M A D A N"
I mean, a person should make a plan, how he / she can properly utilize the time of fasting.
According to Hadith, which I heard this morning is : a person is not encouraged to fast after 15th of Shaban, so as to get full energy to fast (obligatiory) in the month of RAMADAN. which is coming after 15 days.
