Apologies. I mean, constant motivation is a myth.
You cannot for the love of God be motivated and determined every single second of your life. There are going to be times when you feel pathetic. There are going to be people who will make you question your existence. There are going to be incidents that will bridge your happy mind in self-doubt. But, does that mean all of this shall last? No. All of it will pass.
Make you stronger. May be a bit bitter too. But what the hell, every hurt and every writhing anxiety will be worth the triumph.
