"I could never do that..."
"I would do that but..."
"I'm just not (strong or fast or experienced or...) enough..."
It's time to stop!
Stop making excuses.
Stop settling for the known.
Stop choosing the path of comfort.
Stop letting your fear dictate your experiences in life.
Get out there and start!
Try something new.
Do something you've always wanted to do.
Reach for your dreams and goals.
Challenge yourself to be the best you, you can imagine.
Overcome that thing that scares you.
You really can do it if you try.
