Mercury retrograde can be a trying time, and we often experience all manner of mishaps and frustrations during this time. It can be so frustrating that you may think there's no point in preparing for Mercury retrograde. You're just going to get screwed anyway! But that's not true (well, yes, sometimes you will get screwed anyway, but for the most part, you can work to avoid it or mitigate the damages).
Make sure you're signed up for the monthly worksheet so you can keep track of the transit planets every month (including retrogrades!).
Why should I prepare for Mercury retrograde?
By preparing for Mercury retrograde, you can see when trouble spots may present themselves. You learn which aspects will be difficult for you, and which you need to prepare for. By knowing the aspects, you can determine how to deal with them.
Mercury is going to square your Pluto? Pluto is passionate energy, so you know you need to have a healthy, positive outlet for the high energy to avoid power struggles. Mercury is going to oppose your Venus? Venus rules the people in your life, so you know you need to be more considerate, compromising, and work on improving relationship issues.
By knowing the house(s) Mercury retrograde will occur in, you know what areas of life are going to be targeted most. This allows you to come up with plans for dealing with any issues or making adjustments quickly with those areas of life before the retrograde starts, so it's not so bad. And you can plan to use the re-'s of Mercury retrograde - redo, revise, revisit, reconnect, etc. - with those areas of life during the retrograde so you make the retrograde a positive experience.
Mercury's going to retrograde in your 2nd house? Stash some money in case of an emergency, and spend time reconnecting with the present. Mercury's going to retrograde in your 9th house? Make some room and give yourself some extra space, and work on expanding something again.
It may feel better to just ignore when these things are happening, but that doesn't make the planets happy at all. Ignoring it usually makes retrogrades worse! So always keep your eye on what's happening, and work with the energy as best as you can.
Virtually all of the hard, difficult, challenging astrological events that you can experience have the ability to be mitigated and turned around if you get prepared, know it's coming, and know how to handle it. So the next time you think there's no point, remind yourself that isn't true!
And remember, if you ignore the challenging energy, you're not just missing out on a potential opportunity to make things better with that - you're also likely ignoring the beneficial energy. Don't do that to yourself! Be strong, and face it directly. The planets will give you a lot of respect for that, and help you out.
