@MarciknoW what you have to have is a made-up mind, and it's clear you don't have that yet. No judgment because for the longest, I didn't have a made up mind either.
But here's what helped me. I forced myself to work out. I'm not going to say I didn't try to fall off a couple times cause I did. I started forcing myself, and still found an excuse to skip working out for a week and a half. But it stayed on my mind and then I had to force myself to get back to it.
Eventually after so many "false try's" and instances of forcing myself, my mind became made-up and I was able to throw myself into it mind, body and soul. I have a love for it now. I created the love for it in my mind. Now I'm over here jonesing if I haven't worked out for the day. I start getting antsy and I want to work out.
So just keep pushing yourself. I know it sounds generic, but what you're actually trying to do is get your mind in shape, and that happens before you can make a commitment to getting your body in shape. You're trying to train your mind first. So here's what I want you to do after reading this.
Go work out. Do it now. If you're home, do some workouts. If you're close to the gym, go to the gym. But regardless, just go do something now.
