What is the difference between asset and expenses?

What is the difference between asset and expenses?
An asset is something of value that is controlled by the businesses. You may have current assets (items that will be available for up to 12 months) such as cash or office supplies and you may have non-current assets (items that will be available for more than 12months) such as a car. (PS on some non-current assets you will also have to take into consideration the depreciation of the asset)

An expense is outflows that are incurred when used to generate revenue, such as wages, rent, advertising etc. these are all items that the business must pay for in order for them to generate revenue. for example: if running a cafe, if the business operators don't pay wages to their staff, then they will not have anyone to serve customers, which in turn leads them to lose revenue.
