1. Build your own company early on if possible. Only way to really make money.
2. If you must work for others change jobs every 3-7 years. And take your equity with you. The company's success or failure will not depend on you. Really it won't. Companies by their very nature are designed not to depend on individuals.
3. Learn to manage people. Hard job - your success depends entirely on the success of others. Talk about uncomfortable.
4. VC investment is the not the only way to fund your company. VC need the next MS or Apple etc to exist. The chances of you pulling that off are equivalent to buying a lottery ticket. The chances of you creating a company that makes a small number of people an above average return is quite good. A VC will find that a waste of time and exit leaving you with nothing. VC ask you to do something they are unwilling to do. Invest all you capital in one risky venture.
5. Don't be greedy. Easier said than done. If you can get a couple million for part of your equity now and live modestly but comfortably - do it. Freedom is everything - anything more is gravy. If the company does in fact take off the small bit of equity leftover will pay off big anyway.
Good luck
