I am convinced that the only thing in life handed to you is a beat down. I am also convinced that there is only one response to said beat down, you get back up. These things are both very cliche yet very true and I know from first hand experience. Sometimes the motivation just isn't there to get back up, sometimes you just feel like lying in defeat and that's an unfortunate part of life. Even though you don't feel like getting back up, you have to and here's why.
1. You Don't Have Any Other Option.
As my Dad always tells me "You can't let this life get you down." and he's right, you can't. Life may suck right now or a week from now, or even a year from now but, that doesn't mean your entire life will suck. In my opinion, as hard as it is, there is no giving up. There is no waving a white flag and surrendering to the lousiness that is life.
2. You Have People Who Care About You.
Even if it feels like no one cares about you, you are wrong. You have people in your life you want to see you succeed and stand up after life punches you in the face. If you can't stand up for yourself, maybe try standing for someone else.
3. You Deserve A Better Life.
After being beaten down and tested, you deserve to have a better life. You deserve to be happy and to actually live as opposed to just surviving. Your situation might not be ideal but that doesn't mean life won't be in the future. Don't give up your opportunity to be better, to live better, to do better.
