We are all familiar with the phrase 'Nothing is impossible, everything is possible'. The world is full of people who have managed to make the impossible possible through sheer faith and determination.
Its true, when we are determined for something, nothing is impossible in life, only for those who wish not to make some extra steps and actions may seems to have this doubt and challenge in believing that somethings are impossible to achieve in life, it all started from the mindset, what you can conceive from your mind, then you can achieve, hard works also goes along way in this, some will render every required efforts needed for them to make it in life and upon time, they see such coming to reality and success.
You are totally correct and I support you. Just like the bible say ' As the man thinks, so is he' so whatever thing we believe and determine to make it will surely come to pass and we will achieve it but not by merely saying or by feel reluctant but by determination and handworking, we can achieve it, so let's keep our mindset away from negativity and cultivate the positivity in us, that we can achieve or become what we want and it will happen although there might be trials, failure and other, let's bear in mind that before one succeed in life, they fail many time but never gives up hope, so we should also remember that and we will be where we have always wanted to be.
