There are three skills that will set you up for success in life.
Three that will make unstoppable.
1. Learn to write well.
Learning to write as a process of editing and revising over time teaches you to week out your weak, unsupported ideas, and leaves only your best ideas. Writing will teach you how to think.
2. Learn to think well.
Once you've refined your ability to think through your writing you will be able to process the choices in your life, reason things out, and evaluate opportunities and arguments from others on the basis of their merits, rather than the intensity of feelings (yours or others).
3. Learn to communicate well.
Now you are able to use your ability to write and think to communicate in a way that is clear and succinct.
If you can master these three, there is no stopping you!
