My personal point of view through my 8 years experience purely in BUsiness.

Do
- Make more network
- Talk with experience ppl
- Remember your promises to yr client and work on it
- Two steps ahead of your competitor instead of one step.
- Stay work till midnight
- Good in Paymaster to yr supplier
- MANAGE YR CASH FLOW IN ORDER!!! (Very important)

Don't
- Trust anyone except you alone. Make yr own move
- Ever put yor job for tomorrow
- Put your unhappy things to your work
- Be shy
- Just Talk onli...MUST DO ( i hate ppl with a big mouth produce without outcomes )
- Sit office 9-5...MUST GO OUT AND BEAR FRUITS
- Wear unproper uniform even if u r not going out to c client on week day...BECAUSE IT WILL MAKE U FEEL NOT TO WORK
