So, if you can achieve your goal with temporary hardship, if the goal is honest then you will definitely start getting results after achieving the goal. In case of Bitcoin investment, you take temporary pains to take your investment to a certain goal, after achieving the goal, you will start reaping the results from there.
I will view "Hardship, Pain" you say as the Price that investor/Bitcoiners who have low finance ends gotta pay to reach what they aim for. As I would always say that what differentiate some investor from others is there perception about Bitcoin... For an investor that values it such investor will create and align with system that can help him to reach this goal while the other tries to gamble, chill out, call Bitcoin scam, etc.
I have a little different approach to bitcoin from yours. It was before I was thinking in your direction but now a lot have changed for the better and I can boldly say that I am enjoying the process more. Before, I had this mindset that I had to deny myself everything, even cut down on the quality of food and other basic needs to be able to invest in bitcoin. I think this approach is not the best as it will make the journey stressful and full of fear. It is never wise to pay unbearable price to invest in bitcoin so that the aim of the investment is not defeated. There is nothing bad with investing little amount per time instead of starving yourself to buy bitcoin. As little as $15 per week, which is affordable for anyone with a good source of income, and spread across several years will yield something vey big.
