Most implementations of ps take -u or -U (or similar :) to list only that user's processes, so you dont need to filter output through grep. So something like:

ps -u $USER

Would list all of that user's processes. You can choose what information you want to display, too, for example to show the percentage of cpu time being used and the command line arguments for my processes:

cats% ps -o pcpu -o args
%CPU COMMAND
 0.0 /usr/bin/zsh
 0.0 ps -o pcpu -o args
cats%

It has alot of options for sorting etc, detailed in the man page.

So, you dont really need a script to show the processes of a user... but what do you need to script?
