“Problems cannot be solved with the same mind set that created them.” ~ Albert Einstein

Here he is talking about consciousness, because otherwise the problems would not have been created in the first place.
Once you see differently, you act differently. There are a variety of different ways of starting to expand our consciousness.
Firstly start being aware of your current thoughts and feelings, paying attention to what your body is saying to you, how is it feeling?
Notice how you feel when you are enjoying yourself, when you think about the things your are grateful for.
