If you are in a Yeshiva then look around at the various Rabbeim, meishivs…find someone you look up to and think you can grow from. Granted not all Rabbeim are into having a Shaychis with the talmidim but there are many who are and if you seek to make a kesher I doubt you will be rebuffed. Try to set up a learning seder with this Rebbi even a very short one and even if it is only once a week.
Remember, even if its not the perfect fit you always gain from having a kesher to a Rebbi. If your life is complicated and you need someone for advice and guidance then I would tell you to probably seek out a Rebbi who is older and has seen it all because he probably has a lot more experience in dealing with people and giving advice.
Also, don’t think you can’t have a few Rabbeim. You can have more than 1. Lets say one to ask shailos to and one for advice…
At the end of the day the stronger kesher you have to Torah the better off you will be and a Rebbi (if you allow him to guide you and accept his advice) can really keep you on track and save you from a lot of stupid mistakes and problems.
