yes agree, the consolation during the struggling times is knowing that nothing last forever....
i had a friend who used to have a sweet wonderful marriage, then slowly the marriage becomes sour and at the brink of getting divorced. she went drinking alone almost every night, just to forget her sorrows. but when she wakes up in sober, she finds that she is facing the problem again.
she told me that when she's high or drunk she felt happy. when she sober up, she felt miserable again.
she confided in me and i told her that nothing is actually permanent. not that i am so wise but it is the clear nature and fact or reality thats in front of us to see it. and she asked,"really? everything is really impermanent? even the wonderful marriage? even the thought of divorce or quarrels we have? even when i'm drunk i feel happy? even when i sober up i feel miserable again?"
i replied, "yes....."
then i saw that she became silent. i observe....
i see that everyone of us has those times in our lives at some point. including myself.
this sounds like in a movie but life is like a movie you watch "live" kekeee

and it is the first time i ever heard from someone saying to me that she didn't want to ask me or anyone she knows to go out to keep her company. because we all "reminds" her of the good times and bad times she has in personal life. she said that she only wants to see strangers, alone so as to be away from the reality she was actually facing.
ambition or no ambition, having a goal or not having any goal is also not a permanent lasting thing......
today we have this plan, tomorrow we have another plan, time everchanging, situation always change.
i feel that attachment can be a hindrance to actually progress further and tie us to illusion that results in great disappointment when things ripen and explode and not turn out to be what expected.
