I recommend reading [David Goggin's Can't Hurt Me])(https://www.amazon.com/Cant-Hurt-Me-Master-Your/dp/1544512287) if you want get motivated or stay motivated for weight los.
It it he talks about how he went from 300lbs to 180lbs in around a month to qualify for seal training camp.
Very admirable that he has such amazing willpower, however, I wouldn't be able to do it. Reading his book was inspirational for me to take up jogging. So there is that.
I'd read this (or even better the audio book version)
Read this book.
I'd suggest adult education courses and work towards your highschool diploma.
Also just finished reading this book... Might give you some motivation https://www.amazon.com/Cant-Hurt-Me-Master-Your/dp/1544512287
I must be insane, because I just finished Can't Hurt Me by David Goggins and when he was talking about running all those ultra-marathons I was thinking, I want to try that.
And I don't really care for running.
