What Are Your Goal Posts For Determining the Success or Failure of Donald Trump's Presidency?

With so many arguments and discussions occurring over the success or failure of the Donald Trump Presidency, it's worth noting what markers or Goal Posts people consider will demonstrate his success or failure as a President.

For example some people may only consider his presidency a success if he builds the wall along the Mexican border as well as demonstrates a drop in the population of illegal immigrants in the United States. However, even upon achieving this they would still consider him a failure as a president if the economy tumbles down on his watch.

It's also worth noting, if you are a supporter or a detractor of his, what would cause you to change your mind about his Presidency. If for example, a Special Prosecutor investigate and clear or indict Trump of collusion with Russia and obstruction of justice, would you change your mind about his presidency?

And if you think there is nothing that can happen that could change your mind on a Trump Presidency, or if he's already failed or succeeded in your mind, please post that as well as well as why.

Thank you
