You now left the safety of the house which you born, in order to achieve your life's goal, to become a judge. To create law as Moses did, to run the justice liking David, to access power from which the unity has granted, or perhaps a protector for thousands and thousands of years.
You are entering a new world where you are certainly to be successful because you have knowledge. Study has always been our religion duty as Jews, out exclusion from society gives us ability to adapt the others and sense the connection between things which seems diverse. But if you feel that you have power, you are mistaken; if you feel you have the right to put yourself ahead of others because you think you know more than they do, you are wrong. Never allow yourself be driven into the sin of conceit. Conceit is the greatest of the sins, the source of all other sins.
Never give up your religion, not for God, God is the present of all religions. But if your life becomes the struggle through acceptance, you will always be unhappy. Religion may not be perfect, but it is a well built boat that can stay balance and carry you to the other side of the shore. Our life is nothing but a boat drift on water balanced by permanent uncertainty. About the people who you will judge, know this: all that they do is the struggle to find a kind of security, they just people like us, therefore you must not judge the basis of appearance or hearsay. Trust no one, examine all things yourself; do not join with power, despise all rank; do not be ostentatious about what is yours. Owning possession and property ultimately comes to nothing. Possession and property can be consumed by fire, swept away by flood, taken away by politics. Do not undertake what you do not know, this is the cause of anxiety which makes you ill. Exercise discipline.
