- Don't worry about the opinion of anyone beyond your friends.
- Don't worry about prestige. Prestige is the opinion of the rest of the world. If you do anything well enough, you'll make it prestigious.
- Don't be led astray by money, especially when money is combined with prestige.
A test of whether you love what you do is if you would do it even if you weren't paid for it. (Even if you had to work at another job to make a living.)
