1.  You are inexperienced so do not make any expectations in the beginning. The only expectation you can do for now is how much you can work because calculating outcomes is just out of your league in the first year.
2.  No one will welcome you. Competition will always hate you, others either love or hate you and some costumers will hate you too. Do not wonder about what others think, just follow your own way. Those that do not care about you feel free to buy from competition, maybe that’s all their good for and they might not be good costumers in the future.
3.  Focus just one a thing. My mistake in the beginning was to try everything others told me to do. Since I had little experience back in 2006, I lost hundreds of dollars in time and products. Find something you can do or something that you can learn fast and focus JUST on that thing. Once you master it you might consider the next level but only AFTER mastering your current level of abilities. Trust me on this!
4.  No matter how hard you try, some battles are won just when you lose them. Why waste so much time, money, energy with a battle that will bring you little in the near future much less in the long term future? Just let the competition eat the cold meat while you keep grilling the best steak! This is specially true for Advertising bids.
5.  Always update your folder where you save the TOS. It’s not common but it happens when the TOS are updated and you know nothing about it.
6.  Last but not least, if you are going to build your own site, make sure you build it and you maintain it. If you forget you have that site, it’s easy to break the TOS and get your advertising account disabled like happened to me.

And also do not forget that if you are innactive for more than 2 months you might be disabled as well.
