become a herbalist and miner cause theyre the best for makin money then ull for sure have a mount by 40. dont get into alchemy though cause u dont make money, unless u want the potions but it takes a while to make good ones and there still wont be a profit out of it.
and then later after lvl 40 or so u can switch mining to alchemy and once ur a rogue that would be a good proffession to get into anyway.
just my opinion u dont have to follow it if u choose
to bad ur a night elf though cause we always need more ppl on the horde

j/k
