"Life is just a dream on the way to death." 
Geesh, you paint such a depressing picture of life. In that case you are not seeing it's beauty. Life is what we choose to make of it. If you feel like things are just not significant anymore than that's you. Sometimes we lose our way and forget what our purposes are but nothing a little soul searching can do. Eat a hot pepper and spice it up!!!
Honestly my life ain't all that great but I never allow myself to get so low that nothing seems to matter anymore. Someone once asked me what the most important thing in life was for me. I told him that it was happiness and he replied, "Hos ntawm kuv ces yog kuv txoj sia. Yus tsuas yug los ua ua ib zaug neej xwb. " Ever since then...a whole new perspective for me. None of our hopes, dreams, shitty days, stare-at-wall moments, etc. will not be possible without life.
