Synchronicities are coincidences. Co-incident: simultaneous events which are intention-driven as a living matrix of consciousness, continually being co-created all the time.
Synchronicities are the stepping stones which guides you to where you intend to be.
Make your intention, and follow through with action. Pay attention, because one step will lead you to the next. You can learn to see those stepping stones, those events which guide you, those doors which open for you.
Most are utterly blind, it seems, and won't even understand what I'm simply saying, here.
It isn't that hard; it is utterly simple! All of it.
