Patience is actually more than a virtue in my opinion. In fact, it is a key element for success.
First of all, let me clarify that patience does not mean helplessly and passively waiting for something to happen.
For me, the latter is a mixture of laziness, wishful thinking and the like, but it is not patience at all.
Patience implies a certain stamina, self-control and persistence with a focus on the ultimate goal in mind and allowing time to achieve that goal.
For example, a farmer patiently waits for the harvest to come and in the meantime he/she needs to work very hard to cultivate the crops for that to happen.
