Just by being able to pursue whatever symbols you would associate with success is already a great reason for us to feel happy about. Without sufficient health, without being alive, there is not going to be the slightest possibility for us to pursue anything at all.
Thus, it is really possible to feel happy for happiness sake way before we grab the prize we have set our eyes at! And the beautiful part is this. We may think if we attain this this and that, we will be officially recognized as being successful.
But the actual fact and truth is that when we can be happy (at the beginning of our pursuit and right when nobody even notices you) just for the sake of being happy, you are already a true SUCCESS in your very own right already!
