If you try to do everything "right," you will most assuredly not succeed, because there is no absolute right or wrong. Instead, there is what works for you and what doesn't work for you. That may be the same or different from what works for someone else on here, your next door neighbor, or your best friend. It's on you to sift through the information, take what works, and discard the rest. Listen to your body and pay attention to how you feel; if something doesn't work, don't keep doing it, even if a hundred books have been written about it. Blaze your own trail in this journey, and that is how you will have success. Trust your instincts and your intuition and have faith that you can.
And now that you don't have to be perfect, you can be good.
