Joining the CS is not for everyone.

Got to have a very high tolerance for red tape, write, re-write and re-re-rewrite papers and ideas, buying in many stakeholders and many layers of management, exhibit Yes Sir and respectful behaviour while not being seen as lacking in imagination and individual thinking. Manage spanners-throwing and be extremely patient to see the project or policy thru to implementation - often takes years. And have angelic behaviour in all aspects of personal life - don't let go on Facebook and Twitter.
