Name one thing on which you were so firm ,steadfast and adament

OK I will answer this level of question with my qualified academic learning. You need only "ONE THING" for me to name it that subjected to your question's requirements; 1. SO FIRM:- very solidly in place or stable 2. STEADFAST:- resolutely or dutifully firm and unwavering 3. ADAMANT:- refusing to be persuaded or to change Balasari's mind 4. UNYIELDING;- No return of investment. MY ANSWERS ARE AS FOLLOWS; Name: Previously for my clay brick manufacturing. Why? Ineffective of macro and micro view for its business growth strategies. Thanks, Balasri.
