I'm 29F. I think I might need to do a nun mode, at least until the end of June.

I think I need to:

Lose weight

Get better with my grooming and dress sense

Learn to love myself better

Improve in my housekeeping skills

Improve in my music skills, specifically guitar

Stay on top of my work

Any ideas as to how I can achieve these things?

Any other ideas for things to work on during nun mode?
