I love the answer by Dan McNevin! I'm using Git and Dropbox together too now, and I'm using several aliases in my .bash_profile so my workflow looks like this:
~/project $ git init
~/project $ git add .
~/project $ gcam "first commit"
~/project $ git-dropbox
These are my aliases:
alias gcam='git commit -a -m'
alias gpom='git push origin master'
alias gra='git remote add origin'
alias git-dropbox='TMPGP=~/Dropbox/git/$(pwd | awk -F/ '\''{print $NF}'\'').git;mkdir -p $TMPGP && (cd $TMPGP; git init --bare) && gra $TMPGP && gpom'
