Start fresh. I believe it does sounds simple. Though actually, it requires a lot of energy from anyone that wishes to do so. Start fresh. It does not need to be something so big. At times, it might be starting fresh a new blog nor things as simple as deleting the "work in progress" and start it all again, maybe because of one or two things that they feel like lacking here and there nor they trying to make it neater nor even having a new fresh idea.
Starting fresh can be super personal and general. To start fresh, you do not need anyone permission to do so. Things that make you feel good which you do not have that kind of heavy feelings nor sorts of things that makes you feel uneasy are things that may help you to feel at ease. So, go on. Give your best shot! You are all that you give yourself. Best of luck!
