I have invented things, written technical books on software safety in nuclear power plants, designed on spacecrafts, taught Electrical Engineering and Computer Science at the senior and graduate school level as a professor, and I can tell you that the most important skill you can have for live and the work place is the ability to speak and write clearly. If you do not communicate clearly to your audience, your customer, your boss, and your spouse, you will not get what you want and need. English 101 is the most important course you will ever take.
