Life comes with its challenges. Some are easy, some...not so much. Regardless, they will stretch you. They will pull you out of your comfort zone. They will definitely change you.
What makes this process difficult...is experiencing it alone. Strive to include people in your life so that you can continue to build, move forward, grow, and evolve into that which God created you to be.
Yes, do the hard stuff, but don't do it alone.
