Life is made up of The Satisfying and The Frustrating. There are things that work and work well. It feels like you have the midas touch and whatever you touch turns to gold. Things slot into place and everything works in synchronistic perfection.
Then; there is the other side of the coin. No matter how you try to get something to work, it won't. No matter how much blood, sweat and tears you put into something, or someone, it won't work. You try, and try, and try to keep your head above water, but the square peg only finds round holes. In the end you have to admit defeat.
That's the CD Rom known as 'Human Life' for you. For those who only experience all the satisfying or all the frustrating, your life path can be deemed as imbalanced. For those who experience both, you could say you have your 'meat and two veg' ... however, it doesn't take the pain of the frustration away. Its not a good feeling to be getting somewhere in your life (For those who only get the satisfying, stop reading now.) finally, only for it to be taken away from you. All the effort to get it back is to no avail.
More often than not, it indicates something is now most certainly outgrown; its time to read the signs and change your compass direction. If this applies to an outgrown, or finished, job or relationship for example, it is not easy to pick yourself up and re-evaluate life to start again. But shit happens, and it may take you several years for it to make sense why. A big light bulb moment might occur where you realise why it all happened to you. But then again it might not. What is important is to realise that a new set of options will present themselves to you eventually. The best thing to do is be ready for when they do, to grab them with both hands. Hopefully, this will lead to the satisfying in your life; and not more frustration.
But it is what it is ... when something gets outgrown ... it means life algorithm has been activated in your software pathway ... and its time to get over the obstacle.
