Stupidity is listening to others bad advice that won't work for you.
Thinking you are someone else and can be exactly like them.

Hurting yourself by naively believing in other people's lies
and pushing yourself beyond your limits.
Going beyond your point of exhaustion thereby destroying
your inner and outer self, emotionally, mentally and physically.

Doing what you are not designed to do.

Forcing yourself into subjects and activities you are not interested in.

Believing you are bad or worthless because you don't "measure up"
to someone else's standards.
Comparing yourself to anyone or anything and thinking you are and
"should be" equal; for you are NOT equal to anyone or anything else.
You are only YOU and will always be only YOU and no one else.

Expecting every one and thing to be the way you think it should be
and if it's not, go mad throwing fits, temper tantrums and being destructive.

Believing you are going to find some kind of soul mate who is absolutely
perfect and is and does everything you want and like, having no differences from you.

Thinking you can be perfect for anyone else.

Striving to please anyone or everyone by giving up your true self.

Expecting everything to go your way.

Be stiff and rigid in thinking, feelings, movement, habits, procedures, work, anything.
