One thing you may find useful is to shorten common commands such as git checkout and so on; therefore, useful aliases can include the following:

[1] ~/grocery (master) 
$ git config --global alias.co checkout 
 
[2] ~/grocery (master) 
$ git config --global alias.br branch 
 
[3] ~/grocery (master) 
$ git config --global alias.ci commit 
 
[4] ~/grocery (master) 
$ git config --global alias.st status 

Another common practice is to shorten a command, adding one or more options you use all the time; for example, set a git cm <commit message> command shortcut to the alias git commit -m <commit message>:

[5] ~/grocery (master) 
$ git config --global alias.cm "commit -m" 
 
[6] ~/grocery (master) 
$ git cm "My commit message" 
On branch master 
nothing to commit, working tree clean
