Here are a few ideas that come to mind:
Be Impulsive: Allow emotions to control your thinking and behavior. Don’t think things through or look at things from different angles. Remain ignorant and whatever you do, do not read to enlighten yourself!
Have a Negative Attitude: Blame other people for your problems. Especially problems you created. And feel sorry for yourself. Make sure you push anyone away that would offer to help you or give you any kind of empathy.
Be Overconfident: Believe that you know things you don’t actually know and be sure about it. Jump to conclusions. Believe you’re better at things than you really are. And NEVER EVER EVER admit you were not right.
Be Unreliable: Always be thinking about yourself. Don’t show up. Do a poor job. Don't forget to ask others to do your job, if you have one, which you probably don't.
Stop Learning: Don’t read. Don’t continuously educate yourself. Or better yet, make sure you read every truly fake news website you can find, make sure the opinions are so seriously skewed that its either Crazy Left or Crazy Right.
Don’t Choose Your Friends Wisely: Hang around negative, under-educated people and take their advice to heart. Especially if they are Racist, misogynistic or just plain assholes.
Always Try To Fit In: Make decisions based primarily on what other people will think about you. Try to always make everyone like you.
Just. Stay. Clear. And don't Be that person!
