Dreaming about being cheap means undervaluing yourself and everything around you. Learn to value and appreciate yourself by participating and contributing to relationships. Even if all you can offer is to listen, that is more than one more person being attentive to their plight. Ask yourself when and where you can add value to the situation.
When you see a street performer, do you think in your head that it is cheap trick? Reframe from thinking this with wow they spent a lot of time practicing the routine, and now has made your afternoon better. Why not reward the performer with a donation because the performance has value, and you have value to offer as well.
