Reading your post I guess you have explained to what level a person can be aggressive which should be within the person overall discretionary income which the person decide to be investing with comfortably and most come in alignment with your risks level, now two things I consider in my post which investing aggressively within your financial means and also how much of it you can be able to risk which will be different from other people, doing this automatically defines a person level of aggressiveness which the person should go with.
Being aggressive in investing should be completely dependent on the discretionary income of the person. Make sure that you have the necessary backup funds and that you are able to invest consistently. Also, make sure that being aggressive in investing does not have a negative impact on your life. Because, sometimes, being aggressive in investing incorrectly leads to financial problems and a person is forced to take wrong steps in investing.
Never plan to be aggressive in investing by focusing on the market or based on the advice of other people. Rather, consider your position and consider your discretionary income to ensure that you are able to be aggressive in investing or not. If you are not able, then do not take risky steps.
