Seeking Advice on Balancing Love and Career

I am a 21-year-old male, and I know I'm a caring, "green flag" guy. Whenever I try to reach out or talk to any girl, they tell me I deserve better or that they aren't ready. So, I wanted to ask: 1. Should I focus on my career, build myself, and let love come naturally? 2. Or should I focus on my career while also trying to find my soulmate?
