Its really hard to resist for sometimes but if you are really that dedicated then you could really sustain yourself but it will
really be varying on each person because not all would be having the same level or on how they do handle their investment.
I would take that number 4 away, for me it's not part of what would influence your investment for the long term because you are supposed to invest only the money that you can afford to lose, therefore you don't allocate or invest the money that you are supposed to prepare for any emergency expenses.
If we do not manage our money from the very start, well, it would really not help us to hold strong for the long term.
which means that there would really be situations on where they do take out their investment specially if they dont have any options or choices left and when they do know that they do have investment then they will
likely pull it off despite on being on loss.
Hodling is something that is really hard to maintain considering on lots of factors that can really affect on ones decision then this do require that self discipline.
