The sun has just entered Aries this past Friday. You started the square while it was in Pisces, which is not one of the two no-go signs. (Aquarius and Libra are the no-go signs for Sun squares.) You could simply continue with this one, or you could do one this coming Sunday while the sun is in Aries. You can also do one April 5, 12, or 19 so long as you do not start during void of course moon.
If you are doing it to protect yourself from the dollar becoming toilet paper, you could start another one the first Sunday when the moon is not void of course when you are able to get to it--wait until April 26, the sun will be in Taurus and you might just as well continue this one. In the meantime, you could do some of the other meditations until your new Sun square.
Additionally, there is still time--very limited time, but time--to buy silver. If you can get your hands on several rolls of silver dimes, good--quarters and halves are better. Each roll of silver coins is comparable to a roll of true wealth--the type that was once used by banks and governments. You can also buy rounds or bars, if that's what you desire. I suggest, if at all possible, to make a hobby out of it. Collect several different types of silver dimes, quarters, halves, rounds, and modern coins if you can afford it. Bear in mind that this is along with your Sun square, and only you can decide whether the extra bonus from the sun in Aries is worth killing this square and starting another one.
