godly retire?

people say dont kill yourself live gets better, but does life only seem to get better because one simple change seems like ur getting somewhere? what looks go to others may not be what looks good to ourself but because we think if it did someone else good it will fix our lives to, now i cant speak for everyone but meterial objects seem to make me happy but only for a small period of time, but a couple words and memories being made seem to make me happy in the long run. although if both moments are temporay why does one bring happyness for longer? because one was already emotional to begin with, the other can decay physically over time and be physically forgotten. while the other if cared enough about will be engraved into ur head because its not something u can look at its something u have to think about so ur brain will do its best to keep it in long term memories. now with this being said, how does life get better? almost everything in this world is physical, it will decay eventually, you will decay eventually. why start and work into a life that will only bring u temporay feelings? is there a point to this? do we bring our successes to the after life, now if the bible is true we go to heaven if we let god into our lives and accept him and respect him, but as long as we do that we make it to heaven correct? so why are we working to be high and happy if our ticket is just to beleive in god? non of this life matters. im not saying kill yourself but life simply does not matter so why look forward for a better future if it does not matter?
