Do you believe in "signs" guiding you?

I read an article a while back where this person believes there are “forces” or guardian angels that guide you in your life and show you signs to get there. For example one lady kept seeing the same numbers over and over and finally played them in the lottery and won some money. Another person kept seeing the name of a person in variations (last name on license plate, first name on a road sign, etc.) everywhere and then met her soulmate with the same name.
