Many days you will feel weak. Your mind play tricks on you and convinced you that you can't do jackshit. Tell you that you need someone else to live on. Tell you that you are worthless. Tell you that you are a loser.
Dig deep into your heart, tell yourself you have got no other choice but to get stronger each day. You don't need anyone or anything else to live on. You are self sufficient. You owe this to yourself. Keep going.
