Accept your current situation, yes, but you don't have to be happy about it. You can't force yourself to feel good about something you don't feel good about. So it's more about letting go of wanting to change, solve, heal, or understand anything about the current situation you don't like. It's letting it be as it is and completely putting your focus elsewhere -- on your desired reality, and remaining in happiness there.

Here's how I see it. Accepting things as they are helps you to accept all the feelings you resist. So it's basically a way of helping you accept and release resistance and emotional baggage. I've experienced this myself, when I learned to accept things as they are and really accept and feel my true emotions instead of ignoring them and visualizing my life away (wishing things to be different), I started feeling better now and making peace with the now instead of relying on visualization like a drug to escape. My sense of awareness changed, the "now" was no longer Hell, I found a sense of power and wisdom in myself. With the resistance (fear) released, it's easier to tap into that inner vision or intuition that guides you.
