In life, people are going to let you down. This, unfortunately, is an unavoidable fact. There will be people who you went to the moon and back for and they would never think to return the favor when you are in need.
There are people who will take advantage of your kindness. They will lie to you and betray you. They will be nice to you when they need something and then turn their back when they are in a better place.
Although there will be times when this cannot be foreseen, often times it can be. So many times after a situation like this happens, we say that we had a bad feeling from the beginning or that something never quite seemed right. If we learned to listen to the little voice inside our head that alerts us when something is off, we would probably avoid many problems.
I used to ignore the voice in my head, the feeling in my gut. I used to make excuses and tell myself I was “just being paranoid.” I don’t do that anymore and I have avoided a lot of potentially disappointing situations. I now recognize when something doesn’t add up and I move on. I no longer doubt myself or apologize for having standards. This may lead to times of feeling alone or feeling like you don’t really have anybody, but in the end it will reveal who truly values you and is not just there when you can benefit them.
