When we set boundaries, we're often torn between passing up on opportunities and doubling down to work things out, be it at work, romance or friendships, it helps to remind ourselves that when someone or something isn't aligned with our principles and values, doesn't align with our highest God selves, we lose nothing.
Each time I decided to pass someone or something by, I get what I really want eventually. It's not easy because we don't know if we will have better opportunities later, it's easy to say stand firm and reject it automatically, life is full of the grey instead, we can all have a moment of insecurity or a life crisis beyond our control.
So, if you made some unwise choices in your life previously, do not judge yourself, surrender to God and choose self kindness instead.
That is also a kind of boundary with ourselves, a psychological boundary of compartmentalisation, to not let one person or one crisis take over a bright shining future of unlimited possibilities.
