I view any obstacle that gets in my way as an opportunity to learn something new. Here are a few other perspectives on the topic...
"Obstacles are those frightful things you see when you take your eyes off the goal." -- Author Unknown
"If you can find a path with no obstacles, it probably doesn't lead anywhere." -- Frank A. Clark
"Obstacles don't have to stop you.If you run into a wall, don't turn around and give up. Figure out how to climb it, go through it, or work around it." -- Michael Jordan
"The obstacle is the path." -- Zen Buddhist Saying
...and my personal favorite
"A hero is an ordinary individual who finds the strength to persevere and endure in spite of overwhelming obstacles." -- Christopher Reeve
Have a joyful day!
