Perception is everything. You don't need to be good, you need to look good. On a tight schedule, deliver what was asked, and only that, even though you know other things are going to be necessary. When asked to estimate, try your best to give the longest you can get away with. Make it look or sound difficult. At the same time, do the hard work by yourself, figure things out on your own.

When asked to account for your time, use the opportunity to be good at creative writing. Give the most flattering and awesome impression about the time you spent.

Being competent is a pride for yourself only, for all others is whatever they want to see. Always act as if you are making less than you should. Act as, not be. Never stay working late, never work on weekends unless you are the one benefiting.

The value you give yourself will be the value people will give you.
