Motivation is such a strange animal. For most, it means money, for others, it means getting that new car, new boat, new house, either way, it's still money.
In different stages of your life, what motivates you will change. When I was a teenager it was all about Friday night, When I got married it was keeping my wife happy, and when I had children it was providing for them.
Three years ago I broke my neck and spent a long time lay on my back staring at the ceiling lol. Sure, I could have given up, but where's the fun in that? At that point, my motivation was being able to play with my grandson again and that was powerful enough to get me out of that bed and doing physio as hard as I could.
As Lux said, you need an ultimate goal and that goal will change as time goes on. Your goal can be anything you want it to be in this life, it's the best time to be alive. Sure, we have covid, but we don't have the Black Death, poverty is at its lowest ever, you can eat food from anywhere in the world, you can go to places in hours that would have taken months to get to, and technology is advancing at a rapid rate.
My other tip is to pick a goal that's achievable, and then pick a bunch of others that are just possible. Once you hit the achievable goal then the others will become closer.
Good luck, and never, ever give up!
