Oh, maybe because you're of sound body and (reasonably) sound mind, you have considerable gifts and talents, you have all the food you could want, you have a home, and it's a peaceable and happy home, people around you who love and care about you, and, drawing on what you post here, most of the difficulties in your life are 'annoyances'.
Others - they may not be nearly so blessed. Others - the effort that they are making to lift themselves up by their own energies and initiatives - may not be visible to you, but they are making that effort just the same even though you don't see it.
I'm sure you contribute to those less fortunate than you in your own way. And that is commendable and admirable.
My point being - as an example - a small gesture such as overcoming an annoyance, saving your change, and donating it to a charity of your choosing will in all likelihood change someone's life for the better.
They will never know whom to thank, and you'll never know to whom to say 'You're welcome!' but that's unimportant because you would have made it happen.
