Living our dreams is something we should prioritize, however, circumstances, bills and responsibilities sometimes destroy our plans.
Sorry about your Dad's health, I pray he recovers soon. Sickness is not a death sentence, there is hope as far as we are still breathing, anything can still happen..
For sure sickness isn't a death sentence, not all of them at least. But we need to be prepared for it when it comes! So living the now can help to prepare us =)
