Realistic and Optimism – Not be confused with pretending/ignoring just to be happy.

Seeking a realistic perspective is more useful than pretending everything is okay. – In other words, possibly, your current optimism has you believing that the silver lining is the most significant part of the dark cloud, meaning, you might ignore a problem instead of dealing with it in the moment like you possibly should. Be always optimistic, but at the same time, realistic. 

Positivism

Positive thinking isn’t about expecting the best to always happen, but accepting that whatever happens is the best for the moment. – Even if it sucks, it’s reality – Don’t fight it and make a negative mind, you have to be positive… literally no matter what it is.
