Start with one Excel sheet that tracks each stock you invested from all your broker account. You need to track stock symbol, when you buy it at what price, when you sell it at what price (leave it empty if you still hold it), what's the gain/loss, and whether it is a long term or short term investment (for tax purpose). Of course you can easily do so online in each of your stock broker website. However, I would like you to track it again on your own Excel sheet, which gives you much better hands-on feeling.
The you should have another sheet that tracks the overall performance of all your stock accounts on quarterly basis. Have 3 columns for value at the begining of the quarter, additional cash you put in, and value at the end of each quarter. At the first day of each quarter, calculate the annual return of investment (IRR) of the growth of your stock profilio by adding one additional column as the fitting for the value at the end of the quarter. Note that you should not count the additional cash you invested in each quarter as the IRR. Also, calculate the absolute growth of the value from the begining of tracking to current.
Once you start to do that, you will have a clear understanding whether you are hitting 10% annual return or not. If you are not on a consistent basis, you need to do something about it.
