Yh it all balls down to our we reason and reflect on some situations or success when we use the word "mindset is everything". We cannot set our mind at concluding a task and end up not doing that task we earlier planned for ourselves. I know persons that plan their whole day, things to do at each time and where to be at a particular time.
The way our mindset is being conditioned matters most to us all. Our achievement to certain goals in life is also determined by our mindset.
So always remember that mindset is everything.
