When you’re born, like literally an infant - you have no ego, no fears, no worries - you are your truest self. Things like fear, stress and anxiety are learnt as we get older and the world starts to get it’s hands on us.
You are too valuable of a human being to waste so much time being unhappy. Respect yourself and love yourself by controlling yourself. Don’t allow yourself to get sucked into something that isn’t worth your time or energy.
No one wants to give up on something that they have been pursuing for years. No one wants to leave the person they have always envisioned their future with. No one ever really wants to admit defeat. Because all those things mean you’ve failed, right?
