Yuvraj, you can do this!
Just some food for thought / a little bit of inspiration…
GYM: My recommendation on the gym, is that if you plan to go 6 times a week, make yourself go. Get into the routine and habit. If you don’t feel like working out one day, and it takes everything you have just to go to the gym, go and stretch. Even if you are only there for 15 min, it will keep you in the habit and it will help you keep from convincing yourself you can do anything different than what you’ve planned.
FAST: Do everything you can to start and finish your 21 days. If you fall off the wagon somewhere on your journey, get up, dust yourself off, get back in the wagon and continue to the end of your 21 days, remembering how it made you feel. If you fall again, do the same thing. Don’t let yourself get in your own way. This is your fast, your journey. While you have other people on the journey with you, myself included, this is YOUR journey for you to decide if you are going to make it through to the finish line. Think of a race or other event… sometimes it may be about finishing. Doesn’t mean we aren’t a little scraped up and bruised or limping over the final line. Do this for you! You can do it!
I would wish you luck, but you don’t need it. You’ve already started strong on your journey!
