i might not totally agree with you that while investing in bitcoin you should just set up a plan of accumulating 2 bitcoin and use the whole of your life in getting to that planned figure.
Yeah it is of the nature of every investors to dream big about their future accomplishment, so setting a reasonable target is good way to start the process but not every target is encouraged, so actually I would say that having a set target of 2 Bitcoin to achieve in all of his life does not sound like a target because the conviction will be very low and as the time goes you will start losing interest because of the belief that you still have a good number of years ahead of you to meet up and from such mindset other things will come in play and occupy your mind from thinking about your investment, meanwhile as we normally talk about few years targets is better because it gives us the discipline that whatever thing we do we have something very important to reach out and that idea will now be installed on our head.
I personally don't have a set target for the number of Bitcoin that I want to accumulate into the future, because I don't want to put myself into unnecessary pressures to achieve the goal by all means. Although there's nothing wrong with setting a soft target for yourself into the future, perhaps in 10 years time to achieve a reasonable amount of Bitcoin but there's no need to over labor yourself or deny yourself of basic needs that are essential to live a healthy lifestyle because you want to accumulate 1 or 2 Bitcoin within the timeframe.
To me, it seems best to be a bit loosey goosey with your longer term targets, and perhaps if you are brand new to bitcoin, you might want to try to achieve the investment of at least 2 years of income into bitcoin in the next 10 years, and so that would mean that you are aiming to invest at least 20% of your income into bitcoin, yet you might not know how many bitcoins that will get you or what the exchange rate will be or whether bitcoin might go up or down during that time and/or by how much. So you are controlling for what you can, including that you might not even be sure if you can maintain a steady income for the next 10 years, yet you are going to strive to maintain a steady income, which surely is something more in your control rather than figuring out how many BTC you might have had been able to reach in such a time.. yeah, you might still have some ballpark ideas, yet you might still be guessing too much upon too any unknown variables during such time frame.
DCA method for example gives you the ease to accumulate according to your income at any particular time, no need to overpressure yourself and miss out on having a meaningful life by overstretching yourself in the cause of wanting to meet up with unrealistic targets that your income can not accommodate. It'll be unwise to stash your bag with a reasonable amount of Bitcoin in the future then not be in good health or sound mind to enjoy part of it in your retirement or worse don't even be alive to enjoy it. What I focus on is the percentage of my income that I set aside for my DCA method, that is where I have a constant for my accumulation, not the amount of Bitcoin that I must have in my retirement.
Yep.. DCA allows us to choose whether we want to be aggressive or whimpy in our BTC accumulation...and we are able to structure our level of DCA in accordance with our discretionary income, so if we are spending most of our discretionary income on BTC, then that would be considered aggressive. There is nothing wrong with being aggressive, as long as it is not overly aggressive.

The level of your consistency irrespective of you investment amount can as well be seen as an aggressive investment, for example if you are comfortable making use of 50$ weekly or monthly that is your own level of aggressiveness another person can as well be comfortable investing 100$ either weekly or monthly which are all within their level of discretional income since we are all coming in to Bitcoin with different financial status or income flow. However, for me I don't think aggressive investment is proportional to investing under pressure.
Generally speaking aggressiveness versus whimpiness has to do with the level of your discretionary income, so if a guy (Guy 1)has a $2k per month of income, and $1,500 expenses, and if he choose to invest anywhere between $80 to $125 per week that would on the side of aggressive, and if he chose to invest $1 to $20 per week, that would be on the side of whimpy.
Sure there can be differing levels of income and so guy 2 has and income of $20k per month (which is 10x higher than guy 1), and his monthly expenses are $15k, and for him investing $800 to $1,250 would be on the side of aggressive and $10 to $200 per week would be whimpy.
Of course there are other issues with guy 2 in terms of questioning whether his expenses need to be as high as they are, so guy 2 might have a lot of room to cut his expenses, as compared with guy 1 might not have as much room to cut expenses.
