If I Really Want Something

It has been advised by the Ulama of Haq that - when a person is eager to obtain or possess something, he or she can invoke and ask from Allah SWT in doa by using Allah's name:

"Al-Wahaab" i.e. "The Greatest Gifter".

Hence, we can make Du'a to Allah SWT by invoking His name with the quality Al-Wahaab - which is one of the 99 names of Allah.
