Islamic view of Qadar and freewill

How can one understand the relationship between freewill and destiny? We accept Allah (swt) has both written our destiny and has simultaneously given us freewill. Given our premise is correct, it is obvious the latter will consequently be devoid of any kind of value (destiny > freewill) I suspect my personal failure to solve this problem is my definition/perception of destiny itself. To further clarify my queries, I will more or so present scenario.... If an individual was not able to, say get an education, after repeated number of attempts to do so- who would he/she take responsible for their inability to receive an education? Will it be destiny (Qadr) or will be their incapability in the sphere of freewill? As Allah (swt) states that he bestows education to those who seek it, and bestows wealth to whom he wishes.
