I'm often juggling a few books and here is a fantastic one I'm reading at the moment, which I would thoroughly recommend if you've got two X chromosomes and you're interested in what being strong could do and could mean for you:
It's so important to surround yourself with resources and people who support what you're looking to achieve. We all know how demoralising it can feel when you tell someone about a new goal of yours, or something you're working to achieve, and they snub it, or tell you it can't be done.
It may well shake your belief in yourself and whether you can do it or not, and that will then affect your action towards it.
What if you believe unequivocally that you could, or at least you borrowed that belief off someone who had it, temporarily, until you had it yourself? Think of what you could achieve.
