This is one of the most boggling questions that confuses people. This is the question that keeps us from achieving or loosing it all together. There is a saying “Winners never quit and Quitters never Win.” This is just an extension of the well known quote.
A journey of a thousand miles begins with a single step… that right, one who goes is the one who gets (read as achieves). So with all this around I don’t think there will any ways be the point of to do or not to do it’s only going to be “do and more do”.
There is no harm in trying what we have never tried, that is the only way we will get over our fear of failure. We fail only when we don’t try i.e. we quit trying, till we try and we have the strength to improve we can achieve our goal. It’s only that we are living in a frightened world… the fear of failure tends to take the joy of success away.
We have to be bold enough to face our own self. This is the way we are, we know we have to get some where then there is no point in thinking if we have to start or not. What that finally matter is the experience that we gain. Experience that we gain is more important than the end result of the attempt. The thing that lives with us in the long run (our life) is not the laurel that we would gain on victory, it’s the lessons that we learnt and can improve up on and apply further in our life.
