There are too many kinds of human beings...
I believe there is definitely not a single soul that can buy everyone's heart. You will eventually hurt one while helping another.  No matter how hard you try, you can never be the same 100%  in everyone's heart at the same time. We are not perfect! :)

There will tend to have traps, betrayal, lies...
Maybe because of the fast-paced society that make it competitive. Thus, we have no choice but to be crafty. What an irony huh? The more you used your brain & think, the more complicated you will become.

In different phases of your life, you will sure meet someone. That someone who hates you no matter what you do & no matter what you say. OR that someone who gossips behind your back, backstab you in front of all your friends & trying to implicate things between you & another party. OR that someone who only finds you when he/she is in need of attention. OR that someone who is always negative about things around. OR that someone who is only close to you in social media whereas in real life, you all don't even talk! OR that someone who only come to you when he/she knows you are feeling low. (Most likely from social media)...

However, who born to be such a person mentioned above? Noone! We definitely want to be the "good person" in every dramas as we all knew that only being the good person, we will get the all that we want & need. All humans only want, need & yearn for one thing & that is LOVE. When we couldn't get what we need in life, we will unknowingly turn into someone that we will never imagine we will turn into...

You can always find time to reflect on your actions or even asks your close ones to feedback on you. But of course, be open enough to accept critics. Be willing to keep it up or change once you differentiate whether your actions had do you good or bad. Be flexible to changes! :)
