You are not invincible. At some point you’re going to have to sleep! Don’t be too hard on yourself or overload yourself with an impossible amount of tasks. Give yourself time to enjoy the present.
Doing fulfilling work will allow you to be a happy person. It’s up to you to work out the formula for what needs to go into your life in order to enjoy it fully, but when you figure it out, you should fill your week accordingly.
It’s easy to feel a constant pressure to hustle harder and work more, but it is possible to be successful and still have down time.
If you’re not enjoying your present, will you enjoy the future that it’s leading to? It’s normally to have to work hard at something that’s not your ideal to get to where you want to be, but it’s important to find a way to enjoy the journey and the process of achieving your goals. Don’t put your happiness on hold.
