From an astrological perspective, this is due to the Saturn Return

Wikipedia has this entry...

The Saturn Return is an astrological phenomenon that occurs at the ages of 27-30, 58-60, and finally from 86-88, coinciding with the time it takes the planet Saturn to make one orbit around the sun.

It is believed by astrologers that as Saturn "returns" to the degree in which it occupied at the time of birth—approximately every 29.5 years—a person crosses over a major threshold and into the next stage of life. With the first Saturn Return, a person leaves youth behind and enters adulthood. With the second Return, maturity. And the third and usually final Return, a person enters wise old age.

The first Saturn Return is famous because it represents the first test of character and the structures a person has built their life upon. According to traditions, should these structures be unsound, or if a person is living out of touch with his or her true values, the Saturn Return will be a time of upheaval and limitations as Saturn forces him or her to jettison old concepts and worn out patterns of living. It is not uncommon for relationships and jobs to end during this time of life restructuring and reevaluation.

As I've mentioned before on this website, true astrological studies are studies of metaphysical cycles, not the fortune-telling type stuff that the average person believes that it is.

And this Saturn Return is just one of those cycles. But, as I've also said before here, I believe all these (meta)physical cyclic effects are just background effects compared to your focused alignment on what you want.

But because most people do not give much deliberate focus to anything in their lives, they tend to be more prone to the natural cycles. For them, Saturn Return can be a bumpy ride :)
