2) Everyone has his/her own bitchy sides. Just admit this for once. Sometimes, we are easily letting our inner demon consumes us but this isn't a reason for you to let it out of your hand by doing things that hurts others for no valid reason. Use it in a right place and a right time.
3) Don't feel embarrassed to apologizes if you make a mistake. Though you might repeat it again in the future, you're still a human and human makes mistakes. Other humans will always judge you for your mistakes but Allah is there to forgive and love you.
4) Never let anyone take advantages against your weakness. The second of okay comes from your mind might be another greatest weapon that your enemy use to let you drown in misery.
5) Less friends are better. Less friends mean these people are willing to stay in your life because they care and you'll be certainly ended up with a less drama. What's the point of carrying so many cliques but they aren't even your friends from the beginning?
6) It is okay to be snapped sometimes. There's no good to come for holding your anger too many long and it kills your morale slowly.
7) Freedom of words has its own limitation especially when it comes about religion or races topic. So be sensitive. You aren't the only one lives in this world.
8) Rotten apples are everywhere yes but to care and nurture your life with their existence through your daily gossips? Ditch those silly kids straightway. If you act like one, well, realizing your own mistakes is a number one important step to get better.
9) Get a friend that will influence/lead you to be a better person. Though sometimes you may argue with them as many as you guys can, never leave these people behind because it does hard to find good people these days.
10) If you have so many bad things happened in your life and you have no way to go, get a therapist if it is necessary.
11) Every family holds dysfunctional sides. No matter hard things go, never feel give up on them because blood is thicker than water, baby. You are their own family and probably the closest thing that they have. If they act like an ass, why you need to put yourself in the same category as they are? So change.
