No matter how challenging things can be in life, keep going. There are no other realistic options. Never give up or quit. We are all pushed to our limits at times. There seems to be no way out, with no reason to move on, and no solution to whatever it is that is causing us to go through hell. What remains is hope, faith, and belief. But hope, faith and belief on their own often cannot fix the problems and challenges we all face as we journey through our life experiences, but action will. Keep trying over and over again. We will likely, though not necessarily find a solution. When you've tried everything you can, change your approach, your perspective, your angle, and battle onward. Do whatever you can. Just don't stop. I think this is what the saying "If you're going through hell, keep going," suggests. Keep going, because if you can hang in there long enough, ultimately, things can and often will change for the better.
I was having a not-so-good day, then I listened to this song, now "Things Can Only Get Better"!
Have a great day!
