Well if you started in 2017, and then maybe you started with only $10 per week, and then every year you increased it by $10 or $15 per week, then you would be getting close to $100 per week.
No one can ever tell anyone how aggressive that they should be or maybe if they are being too aggressive without having some details of the circumstances, and even with details, the person should be in the best position to figure out these kinds of matters, even if sometimes they might share ideas with others (for example in this thread) to figure out the extent to which they might be able to think about their matter of discretionary income or even how much BTC to try to buy per week in different kinds of ways.
Some details of circumstances are compulsory but I will add one more point that is:
Aggressiveness should be there but not much which affect on the personal life. Let's think if anyone is aggressive and want to invest $100 in Bitcoin every week but he is not caring about his personal life and separating $100 per week. He is not taking care physically himself. So this will not good. Separate that amount to invest which is really separate. In aggressiveness never forget you have your life and your family. Aggressive on that amount which is separate you have.
That is the main goal of a person's income, the extra money after excluding household expenses should be invested in Bitcoin. If you don't accumulate wealth for the future, you may find yourself in dire straits in old age. I think that if Bitcoin can be invested in the present, this investment can be tripled in future generations to make my life comfortable. This could be the main tool to protect against Bitcoin shortages. So it is better to invest in Bitcoin monthly or weekly by following the DCA method.
