You are correct...     First there is always thought, followed by word and action; of course words are action!

 The Decisions we (you) make is the determining factor...   Either to be beneficial or destructive!

  There will always be some good decisions which we should capitalize on and make the hallmark of our existence...  Then there are the bad decision that can wreck or destroy our life; which must be avoided or corrected at any cost!  Plus the stupid mistakes we all make which just complicate our life further...

 The key is to develop your core beliefs so that they line up with the Truth in life...  Then seek the will of God on your pathway of life!  From there it is a matter of using your God given intelligence to hope fully make the best decisions to not effect your life but also those whom you meet on your pathway of existence!
