If only this was true. Its a fallacy and most people are stuck in habits for life.The human brain is not biologically wired to be able to change on a dime, and the ability to do so would be disastrous. Real change is always brought about by external forces, internally its nearly impossible
Try to mentally "restart" yourself. By this, I mean try to reset, at least temporarily, all of your thoughts: your problems, your future goals, your conceptions of your Self. If successful, you'll feel lighter, as if you were at the beginning of a journey and not midway. I think this feeling is universal and you probably know what I'm talking about. That rare moment when the world seems fresh and new. It's elusive but powerful.
Some methods that seem to work, for me at least, are: meditation, immersing yourself in a particular work of fiction (especially a sci-fi movie at the cinema), turning off your phone and Internet connection, and getting lost in a new city.
However, only for you, I messed up learning a lot of things this year. A lot. But not mastered any of it. Learn some of them for fun, some for getting employed as an undergrad, some from peer pressure. Now I can't move back to start those things from where I left.
Appreciate the personal response!
Imagine you are walking through the woods, not 100% sure where you are going, but you turn left, then somebody told you always turn right in the woods (for some reason) and you did, then you got a new idea that you need to go backwards that will help you for some reason... at the end of the day you end up lost without a clue where to go. so you are sitting there in the dark asking how do I restart this level....well... there is no restart button, you are where you are... in the woods... probably alone.
What is also true at the same time - the sun will rise tomorrow, and it will be a new day to try out an find your own way. And it will help a lot to use the experience of the previous day - remembering what you saw, where you took the turn, who you met .... always learning , always moving forward. With this mindset we are never lost in our journey.
In other words, to start over we just need to learn and keep going. Have a great journey!
In zen context -
Don't force yourself to start over. You will start over when you have to. Until then just try to be aware and have guilty pleasure. Some people call it meditation while some call it acceptance. Same thing with different names. Follow your heart, it will never let you down !
Sounds stupid but it felt powerful, all the possibilities what I could become.
