Also asking. Please take note: plants don't usually walk, nevertheless they have a life (their seeds actually propagate with a long stride). It is extremely difficult to give a short definition, maybe the major distinguishing characteristic that (more or less) is unique to life is reproduction with approximation (as an error free reproduction like cloning would lead to extinction in an evolving environment). Warning: 'fire' also has this property, so this definition might entail that fire is something alive. Reproduction is also a direct consequence of death -- if life has to survive -- so this definition stems as a byproduct of the existence of death; sex is, for the majority of species that 'enjoy' it, also a byproduct of death, like the shining side of the medal.

Find what you like doing and that will make your life more enjoyable.

In English we have an expression, "Life is what you make of it." This means that it is up to each person to decide what makes their life worthwhile or better or more interesting. We all have to find our own goals, hopes and enjoyment.
