There is a saying that life is in phases, it is true. Once conceived and given birth to, every human being in life goes through different phases. It starts with growth and development during infancy to later years.
All of this phases come with its joy, attractions, distractions, expectations, desires, and so on. For instance, one of the things associated with infancy and childhood phase is learning and playing with toys. Adulthood is a phase when people think of a career and how best to earn a living.
It is true that every phase has its own demands, desires or even difficulties, it is best to try to enjoy every phase and make the best out of it because once you grow past a phase you cannot get back to it.
