INFPs, when they find a purpose to what they do, are unstoppable.
Your challenge is to find what you really want to do. You have to follow your instinct. Try to be aware of what gives you energy. What feels easy to do. What makes you happy.
( It’s true, you do have to make efforts sometimes and to push yourself out of the comfort zone. But if you succeed in something that does not truly mean something to you, you wont feel satisfied. You will only get empty, temporary satisfaction. )
Listen to your heart.
