We all have limited time to accomplish what we came here to accomplish—and we don't know how much time we have. Making peace with those facts is the first step toward bona fide maturity. The presence of Saturn in your birth sign will be reminding you of this in some way every day. Sometimes this might manifest as a sense of limitation; others times as a sense of urgency. I suggest you take it as an entirely practical matter. You are being invited to take charge of your life, which in the first instance means your time. That's your single most important resource, and you must treat it that way. By fully embracing the finite nature of time (at least as it exists in our consciousness) you will expand your potential into something wider and vaster than you thought was possible. You're likely to become aware that there is something far greater than time or this one lifetime, though what you have is now, and your sense of your mission. The more seriously you engage with your mission, purpose or however you think of it, the more wisely you will use your time. The more you recognize time as finite, the more strength you can draw upon to act on your most deeply held values without delay.
