Who doesn't dream of wealth? It can mean comfort, peace of mind and access to a lot of things that may not be so easy to acquire. Doesn't always come true, but it's one though we all can have and try to work for.
But maybe wealth is not just about money, and you can find it in other things in life. Sometimes you focus on many ideas to find wealth, and you forget simple details of life activities that also lead to that point. Being aware of every experience and learning will provide you life valuable elements so you can take all that knowledge with you and feel fulfilled.
So maybe you won't experience wealth in all its expression, but you can feel close to, if you live life to the fullest.
