I believe that when things fall into place it's a sign.
But I also believe it's a sign when things don't.
Many times in my life I've experienced moments where I should've been less stubborn and pushed less.
There's times in life where we should, and can, push hard towards a goal...and other times when we need to back off and give it a rest.
We won't always know when that is, but a good indication is when you have tried more than two or three ways to solve a problem, or achieve a goal. That is generally a good time to step back and walk away...not forever, just for a while.
Another sign is if no matter what you find yourself in constant distress and repeated road blocks. It may be a sign that this isn't going to happen, or shouldn't happen.
And you know if you push it...it can sometimes turn out badly.
Remember the old saying, 'Good things come to those who wait'...
Don't worry, you aren't giving up on your goals and dreams...
You're just having patience for it!
