I need to change some aspects of my life in order to keep the improvements going. A lot have changed in this past year and now I feel the need to move on, organize myself, work on better habits but I ran into some problems that are not letting me do that.

For some context, 22, studying, working, living with mother. I have nothing I wouldn't leave at a moments notice besides my studies and I want to invest in leaving my mother's house to be able to have my own place, where I can create new habits. Living in this house makes me lazy, messes with my plans because of all the limitations I have in schedule and general organization. Too much stuff, many poor decisions in money spending and problems left for me to solve. I want to distance myself from this bad environment.

With this come some questions, mostly on money management. What percentage of my wage would be a good investment for rent? What advice do you have for anyone in my situation?

This is not related with the game part of TRP, but its a phase of everyone's life and a big step in self-improvement. Independence, self-reliance, taking measured risks and learning to adapt.
