Someone who has wealth beyond the average person is said to be a person of means. Means can also mean the way something happens. You should try to resolve your fight with your brother through peaceful means––noogies are so undignified.
The expression "the end justifies the means" is an example of this usage — basically, you are saying that even if the method used to get the result was bad, the result was good enough to make it okay. The tools needed to do something can also be called the means. You don't have the means to make an art project if you need paint and feathers and you have neither.
