We use the terms 'temporary' and 'permanent' to distinguish the passing from the prolonged. In reality, nothing lasts forever. All is ephemeral. That is worth keeping in mind this, as you assess the importance of an offer or invitation. What matters so enormously now, may prove to be of little or no consequence, sooner than you think. Likewise, something you find hard to justify because of its seemingly fleeting nature may yet turn out to be of great worth due to the enduring memory it creates.
