You are not saying anything wrong John Abraham - and you are actually are probably correct about all of these ideas being somewhat common-sensical and easy to accomplish, so long as persistence and consistency is followed - but in actual practice, they are way easier say than to actually put into practice.

Perhaps one of the most frequent problems that people have is a kind of failure to invest that goes along with a kind of eagerness to either take out profits from time to time and/or failure to keep investing in order to be able to enjoy some of the benefits of compounding, which many of us likely realize that the compounding has exponential aspects that fold upon themselves, but still are likely to take more than just a few years to play out.. so compounding gets bigger and BIGGER .. so the first few times that you might get a doubling it might feel good but then when such doubling comes down the road later, the amounts become somewhat staggering... so there are a lot of occasions that people will pull out way too much of their value and their principle too early and thereafter fail to experience the various doublings (or the exponential aspects of their investments)... 

so that is the problem with failing to invest enough..

and another angle is investing too much and getting too far over one's skiis.. and so over investing has to do with poor cashflow management (and sure sometimes bad psychology too), and if there are not enough preparations for safeguarding various times that cashflows can become short, and then there are times that these people are forced to have  to cash out of some or all of their investment at a time that is not of their own choosing because they failed to adequately account for cashflow shortages down the road that might come from investing in bitcoin today... so then maybe the cashflow shortage ends up coming in s 6 months because there was a failure to keep an adequate cushion or to keep some cash in locations that could be drawn upon during those later down the road cashflow shortages.

So, even though I agree that the principles are easy peasy... but the actual ongoing, persistent and consistent putting them to into practice and tailoring them to individual circumstances is not as easy as you seem to be suggesting them to be.... even guys (and gals) who have been attempting to employ well-balanced practices for years can get themselves into pickle situations - and sometimes these same experienced folks miscalculate the employment of sound strategies may well have to do with figuring out position size rather than all or nothing kind of thinking... especially when it comes to something like bitcoin that some folks might give a thumbs up or a thumbs down, and perhaps there might be some kind of need to still invest at least 1% even with a thumbs down view of bitcoin, and even with a thumbs up viewpoint there still might be a need to make sure not to invest more than 25% into bitcoin, and I am not even going to claim to know what any individual's position size should be, even if my feelings are somewhat strong about getting off zero  and even if I am o.k. with starting out by telling a newbie to consider between 1% to 25% to be a prudent/reasonable starting point for their BTC investment, and in the end they are responsible for figuring within that range where their situation might dictate that they should be allocating and how they are going to manage building their position over time, how long it will take to build their initial position and then try to employ  maintenance once they have accumulated and reached their target levels - and of course, trying to keep learning along the way, too...

Many of us should be way more informed about what to do and how to do it after we have been doing it for 4-10 years, than someone who is just starting out, so then if we have been investing for 4-10 years or longer, then our accumulated position might contribute to our needing to revise our approach based on our having more assets (hopefully including a decent portion of BTC) to help inform us better how to continue to go forward from there, whether it is continuing to accumulate BTC or going more into a maintenance mode, rather than an accumulation mode... and even reallocation decisions might become more relevant for a 4-10 year (or more) veteran as compared to the beginner who might not have anything to reallocate because s/he has not built hardly anything materially meaningful yet... getting up to 1 year or more living expenses (or cashflow) into your investment portfolio starts to become significant/meaningful as compared to the beginner who might contemplate whether to invest 10% to 25% from one pay check that is hardly shit in terms of portfolio building... because 10% to 25% of one paycheck might only constitute somewhere in the ballpark of 1/100th to 1/500th of the annual cashflow... so even by itself, the one investment might seem like a large amount, but it is not really adding up to a significant/meaningful amount of money until it gets to a sizable amount in terms of what that specific person's annual cashflow situation is currently expected to be and then also accounting for what such cashflow expectations might be in the future as well.. There are quite a few places in which normies can end up making mistakes in these various calculations regarding what to do and how BIG of a position size might be reasonable in order to attempt to go in the right direction in terms of accomplishing their goals, whether that is merely to improve their living circumstances, get to fuck-you status or some variation of those kinds of considerations that might merely be to maintain their current living status but not having to work (which is actually an improvement.. hahahahaha.. keep the same living standard, but not having to work.. doesn't that sound good.. and easy peasy to accomplish?)..
