Purpose, it is one matter which makes us matter here on Earth. There are times when we feel like we have lost aspirations in life. We ask ourselves the same questions again and again until they break us. 

Was I called to do this? 
Was I given this body to only feel like a nobody?
What even am I doing with my life?
I think I have lost purpose in living...

Then again, remember this:
“Before I formed you in the womb I knew you, before you were born I set you apart; I appointed you as a prophet to the nations.”
Jeremiah 1:5 NIV

God knew you wholeheartedly before you were ever brought into existence. You were chosen for a special reason which makes you unique. You may not find it now, but soon you will stumble upon it when you're too busy searching for it. 

You are important. 

It only takes strength and perserverance to unearth yourself. You were born with the ipseity to bring to light that hidden responsibility you were called to do so. Why? It's because He chose you and will keep on choosing you even if you seem to not fit the position, if you feel like you can't handle the duty very well, and especially if you don't believe in yourself. He believes in you.

Onward we go mate! Let's keep going even if it's difficult. It's okay to pause, but always bethink, we are not alone in this odyssey of life.
