I think that's a great idea!I agree with this point!
Currently working on improving myself to prepare for the right one when she comes to my life.
Here, I'm going to also say, in a devil's advocate kind of way (because I know some of us can take it too far--I can), that there are limits to isolation and solitude, and that relationships and love can be really helpful and cathartic too--so it's not a hard-fast rule (or I don't know that rule).
It's like a balance of both is needed.
It can be hard because relationships can sometimes help inspire one to work on one's self. They can also be supportive for that--like being in love can help you move through things you need to heal.
I really wouldn't have been able to quit drinking, at least not at the times I did, without the support of important relationships. And that is a bit scary to me because I prefer to think I should be able to do everything on my own. Love and caring relationships can be great catalysts for positive change though imo. But friends and family and idk...maybe pets or counselors can also be healthy relationships that can strengthen your ability to make necessary changes that you want to make.
So just wanted to mention that the idea that you must be alone until you "fix" yourself can also be unhealthy at times...it just depends. Because I've also been there many times--self isolating, which isn't always what someone needs.
But I also find that it's easier to "work on myself" when it's something I actually am excited about working on--something that's been important to me (even if not important to anyone else really). So I find that more motivating than like, being miserable and then being like "I must change X about myself for someone else I haven't met yet." So, perhaps it's the importance of love even in the form of self love or love of life, which sometimes we put to the side for other people...or they can even be cultivated by healthy relationships (self-love and love-of-life).
