@gbenga, thanks for sharing this post, it just serves as a reminder to me of the same information I got from one of the book I read recently.
As wise man must always have it in mind that the overcoming of a certain challenge is a graduation from such level of life and a promotion to another level and phase of challenges higher than the former.
Life is in phases, so when rejoicing on the success of a certain level of life, also prepare for another more difficult phase of life and it's challenges too.
