First you have to figure out who you are, understand yourself, your strong points, your weak points, and what your goals are. What sort of home to do you want?
Then you have to think about what you want in a husband, what are the qualifications in a husband that you must absolutely have, what are the things that are nice to have, but can be compromised on, what are the things that don’t matter very much, and what things would be a “deal breaker” (I imagine smoking would fall into this category for you).
These are very big questions, answers are not always easy. Best to figure this out with the help of wiser adults who know you well- like YOUR PARENTS, or mentor/teacher. There are also dating coaches who can help you work these things out.
When you know who you are and what you are looking for, then you can approach shadchanim, or friends, or anyone who may know guys of that type, describe what you are looking for, and IY”H someone will know a guy who fits the bill and set you up.
