LIFE is a misery or you feel not?

I am a Buddhist. I considered someone who never fails to chant the sutra everyday fully devoted , I am not. At best I will try to keep the Buddha's teaching in mind, if failing to do so, i'll reflect on myself.
In Buddhism, life itself is suffering. Which is why Buddha seek Nirvana to free himself from such miseries & hope to pass down such knowledge to free all sentient beings. But being born as a human is already the 'best' incarnation among all (the animals, beast..etc). Kind of ironic to think about it.
I do not have the best agruement why life is a misery or not. I only believe that since i am born to be human (rather than the lowly beasts) i would & should cherised my life. Since i have to live it, i'll lived it happy and do not regret. I have friends who only thinks that life is suffering, life is hard... Yes no doubt it is but why not think otherwise? If you are 'fated' to live these number of years, live without remorse.
