Take a sheet of paper. On the top of it write "Who I am." Now, and be honest, list all the stuff that you think makes up "You." List all your morals, your standards, your wishes, your desires, all your qualities.
Okay now take a second sheet of paper. On the top of it write "What I do." And list, in order of time voluntarily spent, everything you've spent the last...week let's say actually doing.
Now, and this is the important part. Cross out "What I do" and write "Who I am" on the second sheet of paper and throw out the original "Who I am" sheet because it's completely meaningless and useless.
