“Verily, Allaah will not change the condition of a people as long as they do not change their state themselves” - [al-Ra’d 13:11]
We can only control our "internal" behavior, attitudes and thoughts.
Humans are never in a position to control external sources.
The best we can do is change our own state. It is in fact the only thing we can do.
Success is 99% perspiration , i.e change of state. The 1% inspiration is divine guidance .... I think, which amounts to 100% success.
99% perspiration + 1% divine help =100% success
or from a different perspective
1% perspiration + 99% divine help = 100% success, considering our efforts are minuscule in the grand scheme of things.
And Allah know best.
