If you have the idea of starting a business, you might as well contact your classmates more. Maybe you can team up for the business plan competition.
4. Many things will be found to be nothing when recalled. So, no matter how angry you are, tell yourself that you don't have to do this, and you will find that you really don't have to do this.
