I think wanting a new heart to continue living is a much greater undeniable instinct. Can't you live with less than the amount of money you are making and not sacrifice your core beliefs. Sounds a bit selfish in my opinion to put money ahead of life when it comes to beliefs.
Those decisions should be pretty obvious. If you can't continue to live without major surgery then you shouldn't be here. My own grandfather had 2 triple bypasses before heI died and if it were up to me he wouldn't have had the first one.
Now as for my living situation, I would gladly take less money to work somewhere that is more in line with my beliefs. Unfortunately I have bills to pay and if I were to take a position that was more to appropriate I wouldn't be able to pay my bills. Now before you go running off and saying I should cut back on my expenses, I don't have that many. I don't have cable. I set my heat at 55. I have 1 car with car payment and I don't take vacations. My student loan bills eat up a ton of my income. I do admit I encumber myself with music, but that's one thing I'm a strong advocate for as it educational and improves quality of life. Now if only people could appreciate better music more......
