A few rules I follow:
1. Diversification, have at least 5 positions, preferably 10
2. Don't use margin
3. In general don't throw good money after bad, the stock that looks cheap could go lower
4. For value investment, give adequate safety margin, assume things could go wrong
5. Use trading profits or dividend to start speculative positions
6. Make plans and follow through, don't invest based on "hope"
Some good rules except for #5 which I strongly disagree with based on the fact that money is money, regardless of how it was acquired. The wisdom of entering highly speculative positions will differ with each investor, their current constraints and other things. But not where the money came from in the first place.
Another common investing misconception:
Whether you sell or not has to do with what you paid for it to begin with. I strongly believe what you paid for an investment is completely irrelevant to the decision and timing of the sale (with the exception of tax implications). But people commonly make up rules that they can only sell once it's worth at least what they paid for it or other such nonsense. Once you own a stock, what you paid for it is not important to you or anyone else, only the likelihood of it going up or down from its present value (and other considerations). What you paid for it and whether it's "in the money" is only meaningful in terms of tax implications.
