I shoot for 150 g minimum per day. I also drink a Whey Protein shake every other day if not everyday. I work in a high stress fast paced job so eating the way I want to isn't always something I have a lot of time to do.
Today is a new day. You will get out of it just what you put into it. If you have made mistakes, there is always another chance for you. And supposing you have tried and failed again and again, you may have a fresh start any moment you choose, for this thing we call 'Failure' is not the falling down, but the staying down.
