Not technically 'impossible', but it might just be easier to settle on building a bridge for now. 'Surviving for 100 years' is like 'curing cancer'. Make small, simple goals that you know you can complete. What goals you set in the game are up to you. There is no victory, only glorious deaths. Don't dig too far down, or something scary will follow you back up. Wall off your fortress, or a necromancer will your lunch against you. Don't tell your dwarves to fish they don't know how to swim. The entire game acts as a massive learning experience. Some of them are humorous, but most are a lesson. Everything from harpies to dangerous man-eating carp is everywhere. After playing this game long enough, you'll realize why dwarves don't like going outside. There are a lot of ways for dwarves to die. Starvation, riots, goblins raiders stealing your babies, goblin war parties stealing your lives, elephants, vampires, werewolves, werebears, werebadgers, carp, digging into an aquifer, digging into lava, digging into the nesting area of a Forgotten Beast, selling wood to hippies, insanity, drowning in knee-deep water, and being attacked by your own dismembered finger.
