If It Doesn't Fit, Let It Go
Many times in life we find ourselves forcing things into place. Just as with material items such as with a puzzle, only what is meant to be connected can be fit properly into certain spaces. You can press hard and even if you manage to get the piece to stay within that space, it's still visibly noticeable that something is out of place, especially when the corrected piece surfaces.
Consider this example in comparison to your life experiences. When you try and force things to happen out of season or that shouldn't take place at all, things tend to get thrown off.
Bad relationships, stop good relationships from happening. Consider for a moment all the time spent on companionships that you knew had very little possibility of actually succeeding. But because you know in order to completer your life's puzzle, a good relationship has to be included, you force any resemblance of it into that particular slot knowing that in the long run it'll cause the entire puzzle to be thrown off. What if your puzzle included happiness? What piece would you then put into that space, since you now have a bad relationship that steals it?
Make an effort from here on out, not to force things and people in your life. Life happens but so does learning experiences. If it doesn't fit, let it go.
