50% of ourselves we should give to the world, 50% we should keep to ourselves. That includes our own hobbies, interests, in essence; Life. The 50/50-philosophy that i have worked out. Most of our lives, through school, commercials, doctrines, we are conditioned to unquestioningly give close to 100% at any given time, at all times, like an engine on full speed - not keeping much for ourselves. That is wrong. It is not always wrong to be egoistical - as long as it is done in a healthy manner.
So that when or if something like that happens, we aren't completely ostracised from life. We have a self value. Many people base their existence completely on the other half. And of course i'm not saying one should not be loyal. But by managing our own lives, self-leadership, means that even during the worst crises, we can find some sense of value and self-preservation, the fact that life must go on, and know that there are a thousand fishes in the sea.
Even if one finds that one person one connects with, that is still just one person. There might be, or there usually is, thousands more one CAN find the same connection with. Just, due do the psychological, random and circumstancual nature of our lives, it may take a long time to happen. And of course, that can be a sad thing. But, we should not dwell on sadness, because life itself is a real miracle, it took a huge amount of coincidences just for ilfe to emerge on earth. Finding a true relationship is rare enough without thinking it should be systematized or happen at the snap of the fingers.
One way to speed it up, is to get into astrology. I've found that there is a certain type of composition i am more drawn to. And certain others, i am more repelled by. That does not mean i could not find a genuine and true relationship even with the most "cryptonitic" chart or energy composition, it COULD happen too. But the chance for it is significantly lower. Though, i will say, i am not by far outlearned, i may still be a child when it comes to astrological knowledge. I try to keep learning.
And that is the antivenom to sadness - try to keep an open mind. It is natural to grieve loss. But it is also natural for life to spring out again when the rain is over. New sunny days will appear. One should try to be ready to breathe again when that happens... not stay locked in a hole. It is not fair to oneself. We have an obligation to ourselves. The subconscious mind is often as distant as planet at the other side of the universe .. and we must allow ourselves to drift to that place from time to time, to give our conscious mind time to breathe and relax as well. Not to stay locked up in grief.
Whether that means to see new places, go for a short travel, try new food/dishes, get involved with a new hobby, go for a walk in a forest one has not been to before - it can be a thousand different things. We have an equal value as individuals as when we are in a relationship. That is important to always remember.
