Life is full of growing pains

Instead of focusing on the hurting or the tiredness, focus on the growing.
It is good to want to grow up, and along the way the growing will cause pains, aches, and tiredness. If we look at the growth, we will be encouraged and be able to bear the aches. If we focus exclusively on how we feel, we will be discouraged, sad, and upset.

When your heart and mind fight to be cranky, and you struggle to win the fight and stay cheerful, and you win it, you have a real success to be cheerful about, even if you feel worn out by it. Remember, prayer is the most effective weapon in the fight against a bad attitude.
