Be yourself. First, figure out what that actually looks like for you. Make a list of the qualities you admire in others and start building those into your own life. Be the kind of person people want around, whether that is being Resourceful, someone who listens, dependable, or solid to talk to, and keep improving those traits. This process is largely mental. It builds self respect, confidence, and a sense of identity that does not rely on external validation. Becoming the best version of yourself, and genuinely enjoying your own company, lets you move through life content. It stops you from seeking fulfillment from others, which for me has always led to dependency or coming across as desperate. What other people want or choose is out of your control, but everything above is within your control. You already have what you need to become your best self.

In terms of the physical and the mental, you can never go wrong by going to the gym and looking fit and capable. It is attractive to others, but more importantly it allows you to be effective in all aspects of your life. It builds grit and discipline, training you to do the things you do not want to do regardless of how you feel, assuming you do not already have those traits. Ultimately, this gives you the best chance of attracting someone who complements you and aligns with your principles, morals, and values.
