There is many a gifted child out there who is outperformed by a kid with less talent who tries hard. Effort trumps aptitude.
All skills degrade if you don’t use them. If you’re a weightlifter and you quit lifting weights for a year, those weights are going to be very heavy when you try to pick them back up. I read charts every day, seven days a week. I am on top this stuff.
I associate training with Mars. People train to be the best. They train to be effective. You can use your Mars energy to get what you want in any area of life but you’ll most definitely see it play in the house where it’s placed, and in tandem (for good or ill) with the planets it aspects.
For example I have Mars conjunct Mercury in the 9th house. I train my mind. I constantly challenge my intellect and yours. I am driven to to learn and push beyond limits to see what is over the horizon.
I also train myself in relationship in that I try to manage my impulsive (Mars) reactions to others (Libra).
As another example, someone with Neptune in aspect to Mars may intend to train but never quite manage. The same Mars Neptune could express in any number of ways. For example my husband told me of a priest he knew who was a boxer. He may have had Mars Neptune or Mars Jupiter, see? Or Mars, Jupiter, Neptune for that matter.
While “training” might come easier or be more palatable to some of us, if you are not training anything, you’re probably divorced from your Mars which is never, ever good.
What are you training for and where is your Mars?
