Think positive!

If we think anything negative, you can't await positive. Keep calm and think positive!

Remember that no one is perfect and let yourself move forward.

Change your thoughts from negative to positive: “We are going to have a hard time during marathon" think, “We will face some challenges and we will master it.”

Watch your thoughts, they become words.
Watch your words, they become actions.
Watch your actions, they become habits.
Watch your habits, they become your character.
Watch your character, it becomes your destiny.

Lao Tzu
