Welcome to 3FC!
Baby steps is right!
Make changes you can stick with.
And most importantly, NEVER let a slip-up or a mistake cause you to throw in the towel. NO ONE here at 3FC is perfect. No one! Even those down at maintenance are still making mistakes. Mistakes are not the end of the journey.... allowing mistakes to cause you to give up is the end of the journey.
You're stronger than that! Keep at it! Best of wishes~
