"Think about" is generally used before a noun or gerund, such as "I think about the future" or "I'm thinking about going running tomorrow." There are some exceptions, though, like "I'm thinking about how I made a mistake on my test." However, "think about that all the emotions" is incorrect. In your example, you would use either "about" OR "that" after "think." One example where you can use "about that" is "I thought about that," in which "that" is referring to a noun. I made "personality" plural because you used the word "our" before it, and since everyone can't have the same personality, "personality" should be plural. English speakers usually use the verb "make," not "take," when it comes to decisions, as in "I make good decisions." I changed "one side" to "one or the other" because it sounds more natural. I understand what you meant, but good and bad decisions aren't really "sides." For the last part, I changed it because "completely full" would not be used in this context. I believe you were trying to say that nobody makes either all good decisions or all bad decisions. This was great overall!
