“The only person we can truly change is ourselves through the choices we make”. You cannot change or shape someone to become the ideal partner or “the One” based on your expectations. It’s important you know what you’re looking for before deciding on “the One”.
Regardless of your definition of this ideal partner, there are some prerequisites that are non-negotiable for any relationship to be successful.
Any relationship will require effort to make it successful and to make it last. As long as you lay out clear expectations and are on the same page in terms of your values and expectations in life, you are more likely to have a long-term, successful relationship with that person.
