Hi Kyle,
If you plan on donating, I think donating through UNOS's pilot program for paired liver donation is the highest impact way for an American to donate lobe currently.
I would do a BOTEC for how much benefit the recipient would get versus the expected loss of life to you due to surgery risk and long-term effects.
If you are earning to give, I would check out your employer's policy for time off for organ donation as well as the possibility for reimbursement of expenses through NLDAC (which you very well may be familiar with through your kidney experience).
Would donating prevent you from other opportunities in the future?
