As with all Aces, The Ace of Swords can indicate a new beginning of some sort in your life, possibly on several fronts. Sometimes this new beginning can be started by a separation of some kind - from a relationship, or from a job situation. Know that as anxiety-producing as such a new beginning can sometimes be, that underneath it all is good, beneficial energy that is getting you where you want to go.
In general the Ace of Swords calls on us to not be afraid to make a leap if it's in our best interests. In short, bravery is called for. As the old adage says, "feel the fear and do it anyway." You have a good idea already of what must be done. The hard part is the doing of it. Start today.
Career & Employment
In the context of work, the Ace can mean that you soon will try a different tactic or may even choose to leave the job that you're currently in. If you're committed to staying where you are, you may have some good ideas for new policies or procedures that could make everyone's life easier at work and improve the bottom line/final product. Don't hesitate to give voice to those. Another old adage: "It's amazing what can be done if you don't care who gets the credit." You will ultimately get the credit for anything good that you bring to the table. The credit doesn't have to be instantaneous.
Love & Relationships
In terms of love, the Ace can mean that you are ready to start something new, and if you're currently in a committed relationship, it can indicate that there's something about this relationship that you will choose to put a stop to. Don't hesitate to speak your mind. If something in the relationship is hurtful or bad for you, and you lose your partner because you say so - you haven't really lost, you are being guided toward a relationship that is better for you. Tell the truth.
Finances & Income
When it comes to finances, the Ace of Swords calls us to know when enough is enough. Now is not the time to take chances with money. Don't invest any money that you couldn't afford to lose. You may be approached for a loan. As much as it pains you, it may be in your best interests to not lend what you are asked. You may not be repaid, and your relationship with your prospective borrower could suffer or be destroyed as a result. Lend only if you are willing to take this chance.
Mental & Physical Health
In terms of health, you may finally find it within yourself to stop some bad habits that you know are bad for you. (This can also indicate the converse - finally starting something that is good for you!) Expect some frayed nerves as you're making this transition. Take good care of yourself, only then will you truly be able to care adequately for others. Physical exercise is particularly important now, but don't overdo it.
You may finally let go of a belief system which actually hasn't worked for you for some time. Don't beat yourself up if you find you had been holding some viewpoints and beliefs that you shouldn't have. Everyone makes mistakes or gets hold of the wrong end of the stick from time to time. You will find some spiritual truths that hold more promise for you and which are beneficial. Don't hesitate to talk to others about what works for them on a spiritual level.
