You have the power to choose who will hurt you so be cautious. Emotions are very powerful and whether you believe it or not, it can destroy you.
Remember that at the end of the day, it will be your judgement. You’re the captain of your own life. Don’t depend your future to anybody, they probably don’t care.
Life is bitter sweet. You may be lucky to meet people the same as you are, a person who don’t care if others care about him/her, but just do what they people like doing. Just keep in mind that it is not the ideal world out there.
When you care a little too much over someone but that someone doesn’t feel the same, how would you feel? You’ll feel bad and probably ask why, or what’s wrong. That is normal. But when you go deeper in to that emotion, you’ll go crazy wondering why that is how it is. That’s when you need to STOP! Take a little step back.
