Not to sound delusional, but please pray for grace. Life isn't really about hard work. It's more about alignment, meeting the right people, grace, mercy, and favour.
Never limit your prayers because you think you’re sinful or undeserving. You are not praying because of who you are. You are praying because of who He is.
Watching your dad/mom getting old is something else, it's hard to accept that this person you saw as a superhuman all your life is actually just human too.
